Samsung / Izyico Unauthorized Transaction After 3D Secure Scam

I am writing to file a complaint regarding a fraudulent transaction carried out through IZYICO/SAMSUNG.COM using my virtual Garanti BBVA Bonus card. On 17 November 2025 at 16:04, I attempted to make a ₺499 purchase from ŞOK with my virtual card. During this process, I became a victim of a social engineering scam and unknowingly entered the 3D Secure code that was sent to me. Later, when reviewing my messages and account, I noticed that my card limit had been increased without my consent to ₺26,499 and that a high-value transaction had been executed under the name IZYICO/SAMSUNG. I never intended to make such a purchase, and no product has been delivered to me since 17 November. Despite the clear fraud, Garanti BBVA rejected my objection by relying solely on the 3D Secure usage, and Iyzico stated they were only an intermediary. I reported the situation to Samsung the same day under reference number 8789625, yet I have received no concrete response or solution, and the ₺26,499 charge remains on my card. I request the immediate cancellation of this unauthorized transaction, a full refund of the ₺26,499 charged, and a written official response regarding my complaint. I also expect Samsung and all relevant parties to conduct a detailed investigation and take necessary measures to prevent similar social engineering fraud cases. I kindly request that this matter be handled urgently and resolved as quickly as possible.
