ReelShort Subscription Cancellation & Refund for Charge

I have a problem with an unwanted weekly subscription on ReelShort that I have not been able to cancel. First they charged me 19.99 USD for a weekly payment, and yesterday they charged my card again for 29.99 USD, even though I do not want to continue this subscription and there is no clear option to cancel it in the app. The 29.99 USD was taken from my Veridian card in the USA, and in total these weekly charges are causing me financial loss. I tried about a week ago to stop the subscription, but I could not find any way to contact ReelShort or any working place in the app or on their side to cancel it. I request an immediate cancellation of my ReelShort weekly subscription so that no more money is taken from my card, and I also request a full refund of the last 29.99 USD that was charged without a clear cancellation option being provided to me.
