I was frauded!?

I didn't realize until too late, however, due to a combination of factors (away in the field, traveling, hard to identify item descriptions on my bill from indonesia in general).  So I paid for some jackass hacker to gamble online with my credit card!?!

The shock and silence when the Visa customer service agent on the phone told me what the charge was that I was unable to identify on my visa statement was definitely enough to convince him that I hadn't used my card for that activity... But WTF!?!

I guess I was lucky it was only once, since I didn't catch it for several months... it could have been much much worse!  But I'm still miffed I got stuck with the bill.  I guess I will be more diligent in checking my bills AND following-up with any charges that I don't recognize!
