I've recently come across a problem on my card. Just today to be exact; when I was in the grocery store to buy groceries and found out that I had no funds on my card. So after paying with my debit card, I came home to investigate. Opening up my credit card transaction history online, i've found an unprecidented amount of DDO charges on my card via Valve, on almost -a daily basis-. Sufficed to say, i am quite upset. I've literally just went back through this month alone, and there is nearly two dozen or more charges, when I know full well that I do not game all that much.
I would like to know which game developer under your name is doing it, what can be done, and would very much like a refund to compensate what was lost.
