Dramawave Won't Respond After an Unauthorized Early Renewal Charge

I had purchased a 1-week Premium membership through the Dramawave app. It stated that my subscription would end on 06/12/2026, and I was planning to cancel my subscription this evening, before that period expired.

However, on 06/11/2026, before my one-week subscription period had even ended, another $8 was charged to my Yapı Kredi credit card. I can't understand how I was charged again before my period was even over. After this unfair charge, I canceled my subscription, and even though I contacted Dramawave, I haven't received any response.

I'm requesting both the cancellation of my current subscription and the prompt refund of the $8 that was unfairly charged to my card.
