I got message from the person using aim, Nickboy20048.
We had long chat and I decided to trade my lvl 66 orc warrior with lvl63 warlock.
I tried to log through the wow website, but i coudln't get in.
When I tried to change my account info, it was too late.
The worst thing is that I forgot to close my payment method for wow.
I was using visa payment.
I am really concern if the guy who scammed have access to my visa and use it to buy stuff.
I sent to wow support team for help. I have no clue how to fix the problem. Since I got scammed, I don't even mind to get the warrior back, I just don't want him to get my visa info and use it.
If any1 had same problem or know how to fix it, please send me aim, Jae9088
