Avast Unauthorized Withdrawal

I purchased an Avast Premium product for 42 TL, but without my permission a payment of 599 TL was charged to my Ziraat Bankası card. I did not approve or authorize this 599 TL transaction in any way, and I noticed it only after seeing it on my bank statement and the POS receipt. I tried to reach Avast’s live support through their website but I could not connect to a real representative, so I have been unable to get any explanation or solution regarding this unauthorized charge. I am also dissatisfied with Ziraat Bankası because this payment was processed without my explicit consent or confirmation. I request a full refund of the unauthorized 599 TL charge and the immediate cancellation of any Avast subscription or service that may have been started with this payment. I also expect this transaction to be investigated by both Avast and Ziraat Bankası and for written confirmation to be provided that the subscription has been cancelled and that no further charges will be made without my clear approval.
