  Dexcom's Stelo continuous glucose monitor claims to accurately monitor blood glucose levels. However, when I tested my fasting blood glucose level, Stelo's results were 78 mg/dl versus the results of my True Metrix blood glucose meter of 99 mg/dl. Stelo's results were off by more than 20 mg/dl, which is significant.Separately, I cannot access my Stelo account online. Although I created an account with a username and password, the website refuses to accept my password.On the Stelo app, I was prompted to enter my phone number, but when I attempted to, I was unable to do so.Finally, it is very difficult to get in touch with their product support. Their phone number is not listed on their website.

  Dexcom repeatedly fails its customers and is not taken into account for it. I am on my 4th failed or inaccurate sensor in my current 3 month order which means that due to Dexcom manufacturing subpar items, the cgm that tells my pump how much medicine to give me is inaccurate and the product I pay dexcom to help keep me alive is actually making my health worse. I am out of cgms due to the repeated failures, and Dexcom can only get me a sensor by 3-4 days from my call (called on Saturday, replacement to be sent by Wednesday/Thursday). It is dexcoms job to figure out how to replace these sensors at minimum 1-2 days when their product is at fault for the issues.

  e long wait times and they will call my number back. They have failed to do so a number of times. I have waited on hold for up to 30 minutes more than once, only to be disconnected. I fear that if this receiver is not replaced in a timely manner, it will fail while I'm asleep and not alert me to a potentially life threatening situation. I depend on this receiver to help me maintain a healthy blood glucose level every day. Dexcom has failed to live up to their agreement to provide a timely response to this issue and their failure to do so is placing me in a dangerous situation.Please reach out to Dexcom and help me resolve this issue before I suffer a potential life-threatening situation.Thank you for your help in this manner.

  Ive heard that already. Every time a case is submitted you notify the customer the case will be decided within 1-2 business days. I firstly, wasnt aware a case was being opened, I was told simply that I would be receiving a replacement, which I have not. Please provide the chat dialogue as requested which will prove this. Secondly, said case had to have been opened on June 25 because thats when I received my package and inserted the sensor that didnt work. 2 business days from that is June 27, but I wasnt contacted letting me know that my case is declined until the day I created this case with the BBB, July 4. You have had PLENTY of 48 hours. and the claim I had to file on the second sensor because for more than 24 hours it was throwing incorrect readings that were verified by an independent blood glucose reader, multiple times. I just received email contact that one of my claims were declined, when both are 100% out of my control and on the company. I have wasted money on a product they told me to trash and would replace, but they lied to me and Im out the money. ID ********** is the case they declined even though I followed their support instructions precisely. They wont provide me with the chat dialogue because it would prove they lied to me. You should ask for the dialogue because it promises me a replacement sensor. The lie detector determined that was a lie.
