I Face Unauthorized Subscription Charges From Pdf.com After a One-Time Payment

On 11/20/2025, I made a one-time payment of approximately $1 through the desktop version of the Pdf.com website. While completing this transaction, I did not create any membership or subscription, nor did I give any consent for my card information to be stored or used later for additional charges.
Despite this, on 11/27/2025, 12/27/2025, 01/27/2026, and 02/27/2026, unauthorized charges of approximately $64 each were made from the card connected to my T.C. Ziraat Bank account without my knowledge or approval. I discovered these transactions on 02/28/2026. As soon as I became aware of the issue, I contacted Ziraat Bank, filed a transaction dispute, and completed the necessary reports regarding the unauthorized charges.
Because Pdf.com stored my card information without my permission and later processed these unauthorized withdrawals, I have suffered serious financial frustration and inconvenience. I demand a full refund of the approximately $256 that was charged from my account without authorization, and I also request the immediate and permanent cancellation of any membership or subscription that may have been created in my name.
