DramaWave App Black Screen Prevents Cancellation of 75 PLN Weekly Charge

I am writing regarding non-stop recurring charges from DramaWave that I am unable to stop. Every 7 days, 75 PLN is deducted directly from my bank account, listed with the description "Services". The subscription was not purchased through Google Play, and when I open the DramaWave app to access the subscription management section, I see only a black screen, making it impossible to manage or cancel it.

I am using DramaWave on an Android device. I have tried EVERY method to cancel the subscription, but none have worked, and there is no clear way within the app to stop these recurring payments. Despite my efforts, the charges continue.

I demand that ALL future charges related to my DramaWave subscription be blocked immediately and that no further deductions be made from my bank account for this service. I also request written confirmation that the subscription has been completely canceled and that my payment information has been removed from your system.
