Kuveyt Türk Allowed Iyzico to Charge ₺749 Without My Authorization

I purchased a product service from Iyzico/cvhazirlama.coo site for a one-time payment of ₺29.95 from my Kuveyt Turk account. 14 days later, ₺749.00 was withdrawn from my account from the same company, even though my card information was not registered. Despite my objection, I could not get a result. When the amount was withdrawn, I did not receive a confirmation code from Kuveyt Turk Participation Bank and I was not informed. If such companies can withdraw payments as they wish, then this means that the bank has a security vulnerability. I closed my account and will never work with Kuveyt Turk Bank again.
