Ziraat Bank Card Ending in 7044 Hits With Unauthorized Avast International Charges

On August 2, 2026, two online transactions were executed from my Ziraat Bank debit card ending in 7044 under the name of an overseas company called Avast, completely without my knowledge, consent, SMS verification, or 3D Secure authentication. The first transaction was processed under reference code Avast Avap170503546 for 399.00 TRY, and the second under reference code Avast Avap170507520 for 249.00 TRY, resulting in a total unauthorized deduction of 648.00 TRY from my account.

I have no membership, subscription, or commercial relationship with the company in question. I believe my card information was copied and used without authorization by third parties. As soon as I noticed the situation, I called Ziraat Bank customer service to have my card canceled. The bank representative initially stated, "You probably have a membership with the company"; however, after I confirmed that I have no membership, they directed me to create a separate "Suspicious Transaction Report / Chargeback Dispute" for each item via the Ziraat Mobile application. Following their instructions, I immediately filed chargeback disputes for both transactions.

I demand that these international online transactions executed without my knowledge or security verification steps be thoroughly investigated, that the international chargeback dispute process be completed urgently, and that the unauthorized deductions totaling 648.00 TRY be refunded to my account as soon as possible.
