Several charges from the company on my credit card for 31.52. How do I stop it? How can I get my money back?

Starting in January of 2009, I found muliple low value charges ($25-30) appearing on a credit card with no fraud history. All have been disputed.

While I do not play only games nor purchase online services, it is possible that years ago I bought something from this firm. Therefore I am doubly concerned, someone could be using stolen credit cards to boost their scores in online games, or DRI Tibia Online Game could be illegally mining old customer credit cards, updating the expiration date, and boosting their revenues a bit.
