  I currently have money in my Underdog Fantasy account, but I am unable to access it or request a withdrawal because the company is requiring identity verification that I cannot complete.I requested that my remaining balance be withdrawn and that my account be closed, but Underdog canceled the withdrawal and has suspended my account. I am not asking to continue using the platform I only want to receive the funds that are rightfully mine.Ive reached out to their support team explaining the situation and asking for alternative options or a manual withdrawal, but I have not received a resolution.

  Played their underdog fantasy game, and they marked my slip as a loss even thought the official stats from the league show otherwise

  Business Response

  Date: 06/04/2025

  Underdog settles fantasy contest entries with official league data available at the time of settlement.  When settlement occurred, Magbegor was credited with 7 rebounds by our official league data sources.  Per Underdog's rules, any post-settlement stat correction made by the league will not impact a projection that has been graded.  As such, the statistic in question was settled correctly and will not be re-graded.

  [Your Answer Here]

   

  I would like Underdog to provide a full explanation of exactly when their props are graded postgame. This prop was correctly marked to 8 in their app (as evidenced by my photo) and then manually adjusted back down to 7 even after the Official **** website had her marked down as 8. This is incredibly fishy as the stat correction occurred within a minute or so of the game ending and even updated within my app, yet underdog still believes that using their in house stats and changing them to what they believe is more valid than official league provided stats. Per your OWN TERMS AND CONDITIONS, Underdog reserves the right to make a correction to any slips considering that there was an issue from your stat provider or your app. In this case, your app has had a clear blunder yet you dont take up the responsibility to fix that. I have found multiple instances online of you manually fixing slips at your own discretion to make players lose and was even suggested to take this plan of action by a friend of mine who you also screwed over, yet you went back and manually graded him the win after he filed with the BBB. Incredibly shady and terrible company, cant even abide by their own Ts & Cs and believe that your stats are more legit that official league stats. Also, whats the legality of a DFS app grading off of false stats? Sounds to me like this is the backbone of a massive fraud operation as your company can simply score stats however they want. So tell me exactly when the slips are graded and why my app read 8 rebounds on my winning slip that you refuse to pay out on?

  The customer's entry was settled based off of ******************** available at the time of settlement.  This credited Magbegor with 7 rebounds.  Per Underdog's rules, any stat correction issued post-settlement will not be re-graded.  After review, Underdog's trading team confirmed that the entry will not be re-graded as a result of the post-settlement stat correction.

  I am filing a complaint against Underdog Fantasy regarding an incorrect grading of a fantasy sports entry due to a stat correction that was officially issued by the **** within minutes of the game ending.Details:On June 1st, 2025, I placed an "Under 9.5 PRA" second-half entry on **** player ***** ********. Initially, she was listed with 10 PRA at the final buzzer due to a mistaken rebound credited to her. However, this was a scoring error the rebound was later correctly recorded as a steal (not a rebound), and the **** issued an official stat correction within 5 minutes of the game ********* a result, ********** correct and official second-half PRA is 9 (4 points, 4 rebounds, 1 assist). This correction is reflected on the ****'s official site and even appears correctly on Underdog Fantasys own box scores now.Despite this, my entry was graded as a loss before the correction was implemented, and Underdog has refused to reverse it even after acknowledging that the stat correction was valid. Their reasoning is that entries are graded based on the real-time data feed, regardless of later corrections even when the correction is both immediate and official. I have also never experienced an entry being graded so quickly after the completion of the event. At minimum it takes ***** minutes and up to 72 hours as stated on their website.Desired Resolution:I am requesting that my entry be re-graded according to the final and official stats, as listed on both the **** and Underdog websites. Underdogs refusal to honor corrected, verified stats is misleading and constitutes an unfair business practice especially since the outcome is clearly supported by their own data after correction.I respectfully ask the BBB to help mediate this matter, as the grading error is both clear and correctable.The Parlay was a $10 entry which would pay out $315.50

  Date: 06/11/2025

  Due to the clear and obvious error posted by the ****, Underdogs Trading team revised the stat in question and the customer was paid out the previously mentioned amount.

  My account was permanently suspended after I had made a joke to customer service about my wellbeing if I werent to get a response. I never got a response after and the person assisting me stopped replying. Then each time I had emailed support, they gave no explanation as to where in the rules it was stated that what I said had violated the rules. Each time I had asked for clarification, I was left with no response. I would understand maybe a minor punishment, but to permanently suspend my account after all of the money that I have spent and for how long, I believe was, not justified. I have read the rules and there is nothing in there that specifies that I would get permanently suspended for saying what I did, especially since what I said was at my own expense. They handled this entire situation very poorly.

  Underdog takes Responsible Gaming extremely seriously.  The customer's account was flagged for concerning statements.  As such, the account was closed, the customer was provided with ***************************** and their remaining balance was withdrawn to them. The customer is not eligible for reinstatement at this time.

  My Underdog account (email: ****************************** username: ***************) was suddenly closed without any explanation. I had already placed a $40 bet and had $920 pending withdrawal to my ****** account which Ive used with no issue in the past.Before this happened, I had spoken with customer support and was told there were no issues with my account. So this abrupt closure is completely uncalled for and unacceptable.I expect my account to be reinstated immediately or, at the very least, for my $920 to be returned to me via ******. There is no reason for my money to be withheld without any notice or explanation.Handle this promptly. I expect a response as soon as possible.

  The customer's account was flagged by ********************** for making multiple deposits, and immediately attempting to withdraw with no gameplay.  As such, the customer's account has been closed, and the deposits refunded to their original deposit sources.

  I am filing a complaint against Underdog Fantasy due to their failure to review and reinstate my account in a timely and fair manner. I submitted all requested verification documents, and the information I provided accurately matches the details on my account.Despite my repeated attempts to contact their support team, I have not received any meaningful updates or a resolution. Numerous users in similar situations have had their accounts reinstated immediately after their documents were verified, but I am being unfairly delayed without explanation.This lack of transparency, inconsistency in how account reviews are handled, and the overall lack of communication is unacceptable for a company that handles personal information and financial transactions. I am requesting immediate action to review and restore access to my account, or at the very least, a clear and justified explanation for the delay. My username on underdog fantasy is *********************

  The customer's account was flagged by ********************** due to use of third-party deposit and withdrawal sources, a violation of Underdog's Terms of Use.  In addition, use of a proxy server was detected, also a violation of the Terms of Use.  Documents were requested to verify the customer's identity, and are required in order to proceed with a review for potential reinstatement.  To date, the customer has not fully complied with the request.

  I am writing to file a formal complaint against Underdog Fantasy concerning the sudden and unjustified ban of my account on May 20, 2025, and the subsequent withholding of my legitimate winnings totaling $****** Underdog Fantasy account, with the username [Your Underdog Fantasy Username], was active and in good standing until today. I had accumulated $300 in winnings specifically from making successful *** picks.Upon attempting to access my account or withdraw my funds today, May 20, 2025, I discovered my account has been banned.I strongly dispute the validity of this ban and the withholding of my funds. I assert that all my *** picks, including those resulting in the $300 winnings, were made from a proper and permissible location according to Underdog Fantasy's terms and geographic restrictions.I have already contacted Underdog Fantasy customer support today, May 20, 2025, via support to address this ban and the withholding of my winnings, and to confirm the legitimacy of my gameplay location. I believe Underdog Fantasy has acted unfairly by banning my account without due process, potentially due to an erroneous assessment of my location, and is wrongfully withholding $300 of my earned winnings. This action is unacceptable.

  Underdog's position on this matter remains unchanged.  Due to the Terms of Use violation, the customer's deposit was refunded, and account closed.  This is Underdog's financial decision on this matter.

  After reviewing the situation and understanding more about potential violations, I realize that my use of a VPN while accessing your platform may have caused this issue. I want to sincerely apologize for this.
  My reason for using a VPN was solely for personal data security when connecting to public Wi-Fi networks. I now understand that this action, even if intended for security, could be interpreted as a violation of your terms of service, particularly if it inadvertently masked my true location or interfered with your operational requirements. This was not my intention, and I was not attempting to circumvent any geographic restrictions or gain an unfair advantage. All my gameplay, including the winning *** picks, was conducted from permissible locations.
  I genuinely regret my oversight in not fully understanding the implications of VPN use with your platform. I value the entertainment Underdog Fantasy provides and I am sorry for this mistake.

  Thank you for your time and consideration.

  Sincerely,
  
  ***** ***

  Underdog Fantasy Suspended My Account and Withheld $1,900 Despite Providing All Requested Documentation I am filing this complaint against Underdog Fantasy due to the unjust suspension of my account and the withholding of my rightful balance of approximately $1,900.I have been a regular user of ********************** and have followed all terms of service. Following a win on their platform, my account was suddenly suspended. The reason given was four consecutive failed deposit attempts. However, I immediately provided all requested documentation, including bank statements and pay stubs, to verify my identity and financial activity.Despite my full cooperation, Underdog has refused to reinstate my account or release my remaining balance. I believe this is not only unethical but potentially a violation of consumer rights. I have had no prior issues with the platform and have used it in good faith.This experience has caused undue stress, and I hope the BBB can assist in resolving this matter.

  The customers account was flagged by *********************** Responsible Gaming team after several attempted deposits were denied due to insufficient funds. Upon review of the submitted documents, it was determined that a 12 month suspension of the account would be enforced.

  I uploaded $2000 and was flagged for hedging bets and my account was closed. Cool thats fine and fair if underdog sees as I was doing that. However I didnt make it to where all sides of the bet was covered and I just made it to where if both players I bet on went under I would win something back. Thats only 2 out of 4 possible ways a 2 man could go. I still have not been emailed back on dmd back on X with an update about my initial payment ($2000)

  Business Response

  Date: 05/18/2025

  The customer's ********************** account was restricted due to bonus abuse and hedging fantasy contest entries, violations of Underdog Fantasy's Terms of Use. As such, the account was closed. The refund was canceled and winnings were forfeited due to the violations.
