I Face Unauthorized ₺795 Charge From PDFSimpli After One-Time ₺39.90 Payment

I used PDFSimpli to get one-time support and paid ₺39.90 for the service. I never agreed to any subscription or recurring plan. However, I was shocked to discover that my credit card was later charged an additional ₺795 without my approval. At no point was I shown a clear consent screen or subscription agreement that authorized such a payment.

This feels like a hidden and unauthorized charge, and it left me questioning whether the company intended to withdraw this amount every month had I not noticed it in time. I immediately checked my account and canceled any possible subscription, but the money taken from my card has not been refunded.

I expect PDFSimpli to immediately refund the unauthorized ₺795, cancel any hidden membership tied to my account, and ensure that no further charges are made without my explicit permission. Charging customers without consent is unacceptable, and this issue must be resolved promptly.
