UPDATE: called Blizzard this morning, only had to wait 2 mins to talk to someone and they recovered my account and reset the password.
Logged in to see what the damage was, I still have all my items but they took all my gold and there seems to be a new person added to my friends list, the name is a couple of Asian characters.
Looks like I won't be playing much anymore since I have zero gold and can pay for repairs...
