I Canceled My ReelShort Subscription but the App Kept Charging My Credit Card $89.97

I am writing regarding unauthorized charges from ReelShort on my credit card, despite cancelling my weekly subscription within the first week of use. I cancelled the subscription around 15 November and did not give any further consent for renewals or additional payments. Although the subscription was cancelled, I keep receiving charges from “ReelShortW-1214481759 SUNNYVALE” on my credit card issued in Saudi Arabia. So far, a total of USD 89.97 has been charged after the cancellation, which I did not approve. I request that all charges made after my cancellation be fully refunded and that my subscription and any future billing be permanently stopped. I also ask for written confirmation that no further payments will be taken from my card.
