A Purchase Was Made On My Card by Iyzico Without My Knowledge

Late at night, I saw a charge of ₺4079 on my account from a company named iyzico/ITX Turkey Perakende. The transaction took place at 4:44 AM, and I had no idea it was happening. I was completely unaware of this platform until now, so discovering a significant amount withdrawn without my consent was truly surprising and distressing. I reached out to my bank right away, but the process is dragging on and lacks clarity. I request a complete refund of the amount at your earliest convenience. This payment was not authorized by me, and it feels unjust for someone to take advantage of my account in this manner. If this matter isn't addressed promptly, I will take the necessary steps to ensure my rights are upheld.
