DramaWave Unwanted Subscription – Refund and Cancellation Request

I recently discovered an unwanted Dramawave subscription that has been active for about 2–3 weeks. During this period, I have been charged a total of 17.91 EUR without my clear consent. I tried to cancel it through the app, but the Dramawave app does not even appear in my mobile app list, so I was unable to manage or cancel the subscription from there. Because my phone does not allow screenshots, I cannot provide an image of my bank or operator statement, but the Dramawave charges are clearly reflected there. I have not yet contacted Dramawave, my operator or my bank, because I expected the cancellation process through the app to work, which it did not. I request an immediate cancellation of this unwanted Dramawave subscription and a full refund of the total 17.91 EUR that has been charged. I kindly ask for this issue to be resolved as soon as possible and for written confirmation that the subscription has been cancelled and no further charges will be made.
