ReelMira Unauthorized Charges of $24.99 and Refund Request

I am writing regarding unauthorized charges from the Reelmira app, which I accessed through Facebook. Today I noticed that my card has been charged 24.99 USD multiple times by Reelmira, even though I had already changed my credit card details and did not approve these repeated payments. There is no visible or accessible customer support contact for Reelmira within the app or via Facebook, so I have not been able to reach anyone to resolve this issue directly. I request that all incorrect and unauthorized charges of 24.99 USD made today be fully refunded and that my subscription or any active payments related to Reelmira be immediately cancelled so that no further charges are taken from my card.
