Problem Canceling BetterMe App Subscription

I am writing regarding my BetterMe Fitness subscription, which I purchased directly through the BetterMe website using my bank card ending in 7318. I have been trying to cancel my subscription, but the process on your website does not work as described. Today I followed the cancellation steps on the BetterMe site, and at the last step it states that an email will be sent to complete the cancellation. I tried this several times, but I have never received any email from BetterMe to finalize the cancellation. I have full access to my email account and I have carefully checked my inbox, spam, and other folders, but no such message has arrived. In the past I have also tried to cancel my subscription and could not figure out how to successfully complete the process, and during this time I have continued to be charged. I also contacted BetterMe support through the in‑app option, but I have not received any response so far. As a result, I am stuck in a subscription that I am trying to cancel and I am worried about being charged again against my will. I request that my BetterMe Fitness subscription be cancelled immediately and that you confirm in writing that no further renewals or charges will be made to my card ending in 7318. I also ask you to review the previous unwanted charges that occurred while I was unable to cancel and to handle them fairly. I expect a prompt resolution and a clear confirmation of the cancellation.
