DramaWave Weekly Charges Cannot Be Cancelled on Android

I am writing regarding recurring charges related to the DramaWave service that I have been unable to stop. Every 7 days, 75 PLN is taken directly from my bank account, and the transaction appears under the description “Fictional Services.” The subscription was not purchased through Google Play, and when I open the DramaWave app and try to access the subscription management section, I only see a black screen, so I cannot manage or cancel anything. I use DramaWave on an Android device. I have tried all the suggested methods to cancel the subscription but none of them work, and there is no clear way to stop these recurring payments from within the app. Despite my attempts, the charges continue. I request that you immediately block all future charges connected with my DramaWave subscription and ensure that no further debits will be made from my bank account in relation to this service. I also ask you to confirm in writing that the subscription has been fully cancelled and that my payment details have been removed from your system.
