I Face Unauthorized HBO Max and London Charges on My Card
On March 30, 2026, at 10:29 PM, a transaction of $9 appeared on my Garanti Bonus credit card under the name “Iyzico HBO Max,” even though it does not belong to me. Within the same minute, a second transaction of approximately $330 from a London-based source was also placed on hold on my card. These transactions were carried out completely without my knowledge or consent.
As soon as the situation was noticed, Garanti Bank immediately blocked my card to prevent further unauthorized charges. However, I was informed that the higher amount transaction is still pending and that I can only file a formal dispute once it is fully processed. When I tried to contact Iyzico and HBO Max, I was unable to reach customer service or speak to any representative.
First of all, I want to clearly state that the $9 charge under “Iyzico HBO Max” is not mine and should be evaluated together with the approximately $330 London-based transaction that occurred at the same time. I request that Iyzico conduct a detailed investigation into these transactions, recognize them as unauthorized, and ensure that all amounts charged or pending are canceled and fully refunded. I also request detailed information regarding these foreign-based transactions and how they were carried out.
