Netflix Charged Me 5 Times Without a Valid Subscription - Refused Full Refund

I wanted to open a Netflix account to watch movies, so I attempted to subscribe. After completing the payment process, I received an error message stating the payment wasn’t processed. I tried again, but it still didn’t work, and I was told it was a system error. At that point, I decided to give up on the process entirely and never logged into the account again. However, when I later checked my account activity, I discovered that five monthly payments of ₺299.90 (around ₺1500 in total) had been automatically withdrawn from my account. Despite never completing the signup, these charges were made without my consent. I contacted Netflix customer service twice. The first time, they said the refunds were processed, but I only received one payment back—₺299.90—over the following two months. On the second call, I was told there had been an issue and that they re-processed the refund, but now another month has passed and I still haven’t received it.
