YouTube Premium Double Charges for Three Months

I have been using YouTube Premium through the Apple App Store and since June 2026 I have been charged incorrectly. For the last three months, June, July and August 2026, YouTube has taken two separate payments of ₺319.99 from my card for each month via Apple.com/Bill, even though this should have been only one subscription fee. In total I have been overcharged by approximately ₺960. In addition to this, my subscription was cancelled against my will and without my approval. When I contacted YouTube about the double charges and the cancellation, they told me that they were not responsible and that Apple Store was handling these payments. When I contacted Apple Store, I was told that there was nothing they could do, so I was left without any concrete solution even though the problem is clear on my bank statements. I also have several bank receipts from Ziraat Bank showing these Apple.com/Bill charges as evidence. I request that all wrongly collected fees, totalling around ₺960, be refunded to me as soon as possible and that an explanation and apology be provided for how this double charging and unwanted cancellation could occur. I expect my grievance to be resolved quickly and in a way that prevents similar issues from happening again.
