Lets say you have a friend in another server that wants gold but cant do dailies or famr =)
1. You use a diffrent credit card then the one on your account ( havent tried with same one) and transfer your char to the server.
2. GIve your friend his gold and w,e else he needs.
3. Call blizzard and tell them someone hacked your account and transfered it.
4. They will return your char back to your server by "reseting him" and you will get all your gold back. This also allows your friend to keep your gold as well as getting refunded on the transfer since you are not actually there.
I have done this 1 time on my account and with 2 other friends and it has worked both times. If you dont get refunded you can call back and say my friend tried suprising me with a server transfer that i dident want or something. Tell me if this is a repost.
TY AND GL
