Complaint: 22036272
I am rejecting this response because:the company never responded to my emails or calls that I made directly to the company, emails came back and the business phone service was full and they did not answer or return the first message I was able to get through with. I stopped credit card payment due to the extended delay period of response and delivery time.

Grill Rescue Company order# GR503847 order placed 5//27/24 for a grill cleaning brush/pad; paid additional to have item shipped next day; after 3 days and no shipment I contacted the Grill Rescue Company via email; they have a phone number but nobody answers; during the next several days I sent 2 additional emails asking shipment status, an emails response from Grill Rescue said the item had been shipped but the shipment couldn't be tracked; even though I paid extra for next day shipping the product took 14 days to arrive; I spoke with my **** letter carrier at the time of delivery on June 10th, she stated that I could refuse the shipment and have the item "returned to sender" so I did refuse the item; she notated the refused shipment and kept it in her mail truck for "return to sender'; Grill Rescue Company is still refusing to credit the $59.54 charge; the customer service and lack of customer communication with ********************** Company is a sign that they will not survive much longer as a company!!!!Business Response

I placed my order on June 8, paid extra for it to be shipped on the next business day (June 10), only to have it not ship until July 5 and arrive on July 9. When it arrived, it was still missing an item, the dunk tank. The business does not answer the phone number listed on its website and its email inbox is full. Based on comments on their ads on ********* there is nothing unique about my order: many people had their order delayed by a month without explanation and the dunk tank was not included in their order. The company has failed to respond to repeated requests for updates but continues to advertise heavily on ********* It's a shame because they do have good products.Business Response

Complaint: 22035054
I am rejecting this response because: I don't believe that the missing item from my order has shipped. I have yet to receive tracking information for the shipment. Further, as seen in the attached screenshot, I received a message from the business on ******** today indicating that they had not yet received their shipment and thus do not have product to send to customers. It has been 59 days since I placed my order. I would appreciate an honest answer with an actual expected timeline of when I will receive my order.I'd also like to see them indicate on their website and in the Facebook VIP group that certain items are on backorder (just be honest and upfront about it). Instead, they continue to advertise deep discounts for products that they aren't prepared to ship in a timely manner.
Again, this company has good products, but terrible customer service.

I purchased 3 Grill Rescue brush sets on May 25, 2024 with the understanding that if I was dissatisfied with my purchase there was a full money back guarantee- minus shipping costs- for both used and unused product. I tried the brush out- it was not at all acceptable and I contacted customer service about wanting to return the entire sets. I have emails dated June 10, 11, 13, and the 14th trying to set up a return. I was told to send product back and send them the tracking number which I did on June 18th. It was delivered to Grill Rescue on June 20. I sent another email on the 26th of June asking the status of refund. No reply. I have tried over and over to call and the phone number just has a message that their phone support is limited and to contact by email. I have done that repeatedly with no results. I have yet to receive my refund and am very dissatisfied with the poor customer service of this company. I would like to receive my refund and be done with this matter.Business Response

Purchased a grill brush from this company in July 2023. It was obviously defective and kept falling apart. Others have reported the same defect in website comments. The brush head does not properly fit into the brush handle. I reported the problem, sent them information including photos and videos. They admitted there was a problem and sent me a new brush head but refused to send me a new handle so it did not solve my problem.Business Response

I am rejecting this response because: I did receive a replacement head as you note in your response. That resolved the issue of the head falling apart. But the head also falls off the handle with very little pressure, it does not seat correctly into the handle. I've asked for a replacement handle and have been refused.

Hi *******,
Im really sorry to hear that the replacement head is still causing issues by not seating correctly into the handle.

On June 6th I saw an ad on ******** for a grill brush the Rescue Grill Brush And I thought what a perfect gift for my husband for Fathers Day or his upcoming birthday. I proceeded to buy a bundle they were offering for 1 brush with a scraper, 1 dunk tank and 1 hanger. I also ordered grilling gloves, 1 replacement head, and even a box for it all for an extra .45 cents. The total being $127.01. I have reached out multiple times since then asking when I would receive my order, since they have collected their money already. Today is July 23, Ive reached out many times and I keep getting an automated response from them with no resolution. *** asked for a refund about 3 times. I find this unacceptable. I would love a refund, I believe Im not the only customer theyve done this too so I thought it necessary to come to this point.Business Response

I purchased a grill rescue bundle that included the metal scraper head, dunk tank and a hanging attachment for the brush itself. This purchase was made on 7/9/24. I received and order confirmation and the funds were deducted from my account. After the expected 1-3 business days for my item to ship I checked on the website on the status of my order. The site specified "can not find order". I have not received any response from customer service in my multiple attempts outside of automated emails indicated my complaint has been received. The website itself encourages me to shop with them instead of amazon, as well as indicating that they have " Sizzlin' Support" with 4 easy ways to get in touch fast. The support phone number is listed on the website but has a voicemail that indicates they no longer accept calls. I have sent multiple emails over a period of days and still have received no tangible response. My email provider is also indicating that my emails are not being received as the recipient's email is full. As it stands, I am not even sure how to go about requesting a refund as the company seems uninterested in resolving my issue. There seems to be only one avenue to reach customer support, so I don't know why the site still advertises there are four. I feel that my only option at resolving this will be contacting my financial institution to contest the charges. I absolutely feel mislead by the customer experience that I was advertised.Business Response
