Dramacove Charging My Card Without a Subscription

I live in Goiás, Brazil, and I am being charged by Dramacove even though I have never made any subscription or registration with this service. The first charge occurred on 20/10, in the amount of 156, and after that I started to receive weekly charge notifications, to the point that I had to block my card to avoid new debits. I contacted my bank about this unauthorized charge, but they informed me that nothing could be done, and I could not find any official contact from Dramacove to request cancellation and refund. I do not recognize this service and I never authorized these payments. I request the immediate cancellation of any subscription or recurring charge in my name or on my card, the complete refund of the amount of 156 that was charged without my authorization, and confirmation that no new debits related to Dramacove will be made in the future.
