ReelShort Weekly Charges Continue Without an Active Subscription

For the past 24 days, I have not had an active subscription with Reelshort, yet I have been charged 29.99 every week. These payments appear on my account as transactions to ReelShort in Sunnyvale, California, and I have screenshots clearly showing these charges. I contacted Google support first because I use Reelshort on an Android device, but they informed me that these payments were not processed through Google Play and are directly related to Reelshort. I then contacted Reelshort, but they responded that they would never make such charges, even though I shared screenshots of the transactions. I request that Reelshort immediately stop all further charges to my account and, if possible, refund the amounts that have been taken without a valid, active subscription. I also ask for a clear written explanation of how these charges were made despite having no subscription.
