Edit.pdfs.com Unauthorized Charge Attempt

I made a ₺1.5 transaction on edit.pdfs.com, but later that night, an unauthorized attempt to withdraw ₺3,500 was made from my account without my knowledge or consent. It is clear that my card information was compromised after using this site.

I had to immediately cancel my card to prevent further fraud, and I am now considering filing a legal complaint. How can a website handling small transactions suddenly attempt such a large unauthorized charge? This is highly suspicious and must be investigated.
