Cancelled Avast Cleanup Premium Subscription Triggers Unauthorized Auto-Renewal Charge

I previously purchased an Avast Cleanup Premium subscription of my own accord through Avast and used this product, which was listed at 42 TRY at the time of purchase. Afterward, I cancelled my subscription through my account, believing that it would not renew and that no further charges would be drawn from my card.

Despite this, on July 11, 2026, an unauthorized deduction of 599 TRY was made from my Ziraat Bank card without my permission or consent. I only noticed this transaction on July 21, 2026, while reviewing my account statement. When I attempt to reach live support on the Avast platform, I am continuously redirected to knowledge base articles, making it impossible to connect with a real customer service representative, and no solution is offered for my issue.

I absolutely do not accept this 599 TRY charge being drawn from my card after having previously cancelled my subscription. I demand from both Avast and Ziraat Bank a full refund of this unauthorized 599 TRY fee and the complete, permanent cancellation of this subscription. Furthermore, I request that my bank conduct the necessary review regarding this transaction executed without my consent and implement measures to prevent similar recurrences.
