Heh, happened to me 1 month ago. After 1 month, my account is still frozen with a few thousand USD in it. I have done everything they asked me to.
I will be posting shit about them in every thread about mtgox I see until they give me my money back.
I asked them to transfer the money to the same account it came from (in case they think I stole it), but no they need this, then that, and every time it takes a week or two.
I hope I get my money back before 2013.
