Small money amounts vanishing – No transaction records

Description

Greetings, I have a question regarding my current balance. On october 28th I bought some games from Fanatical.com, cost was 89 euro cents and that transaction went without a problem. My question is what happened to my balance after that, to be more precise, next morning I noticed that additional 2$ were taken. Day after, it was 7$, and this morning additional 2$. Around 10, 11$ or so where taken and there is no transaction report that shows who has taken that money. I would like to have an explanation to what is happening here, where did my money go and how to get it back, if I am being robbed by someone, etc. I dont have recurring payment or anything like that and I tried customer support, but since all is automated I keep hitting the brick wall and nothing is getting solved or answered. Thanks in advance!
