I Face Unauthorized Subscription Charges From Pdfe.com After Buying a CV Service

I accidentally discovered that large amounts of money had been charged to my QNB Finansbank credit card by a website called Pdfe.com without my knowledge or approval. In January, I had only saved my card information on the website to use a CV preparation service, and I noticed three small charges of approximately $1 each, which I assumed were normal fees related to the CV service. However, I later saw on my credit card statements that on January 12, February 12, and March 12, three separate charges of approximately $67 each had been made. On the website itself, the transactions appear as approximately $64 each, but the actual amount charged to my card was approximately $67 every time.
I never approved any membership, subscription, or recurring payment for these large amounts. I believed I was only making a small one-time payment for a CV service, yet these amounts were charged regularly from my card for three consecutive months completely without my knowledge or consent. On the day I discovered the issue, I immediately canceled my membership on Pdfe.com. However, I could not find any accessible representative, clear communication channel, or customer support service on the website.
I have not yet contacted QNB Finansbank regarding these transactions because I could not find a clear section in the mobile banking application for disputing charges from previous billing periods, and I was unsure how to proceed. Therefore, I request that all charges made on January 12, February 12, and March 12 without my knowledge or approval be canceled and fully refunded to me.
I also want my financial loss caused by these unauthorized recurring charges — which were processed as if I had an active subscription — to be urgently resolved. In addition, I request that my card be secured against similar unauthorized transactions in the future and that a detailed investigation into these payments be carried out if necessary.
