Need Refund From ReelShort

I purchased a Reelshort “cup weekly” subscription today through an ad on Facebook, paying 19.99 USD via Apple Pay. Although the amount appears on my bank account, my Reelshort account does not show any active subscription under purchases. When I check inside the Reelshort app, there is no subscription visible, and I cannot use the weekly subscription I paid for. The transaction on my bank side is linked to Reelshort, but it is not reflected in the application. Facebook support has informed me that this is not their responsibility and that I should contact Reelshort about the issue. I request that my weekly cup subscription be promptly activated on my account or, if this is not possible, that my payment of 19.99 USD be fully refunded. I would like this issue to be resolved as soon as possible.
