Avast Deducts 648 TRY From Ziraat Account 1146-102975723-5003 Without Approval

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 number 1146-102975723-5003.

I have no membership, subscription, or commercial relationship with Avast. I believe my card information was copied and used without authorization by third parties. As soon as I noticed these transactions, I called Ziraat Bank customer service to have my card canceled. The representative initially suggested that these charges might have been incurred due to an active membership; however, after I confirmed that I hold no membership, they advised me to submit a separate "Suspicious Transaction Report / Chargeback Dispute" for each item via the Ziraat Mobile application. Following their instruction, I immediately filed chargeback disputes for both transactions.

I explicitly demand an urgent investigation into these international online transactions executed without my knowledge, consent, or basic security verification steps, as well as a full refund of the total 648.00 TRY deducted from my account.
