I've been ignored for nearly a week. Ticket's been closed twice with no response.
I had an issue with my account following the security breech, submitted my ticket, waited 3 days, and received a reply that it was taken care of, and it was resolved to my satisfaction.
This was all done through their support.mtgox.com service, I did not have to send any personal mail, etc.
Your not the only one who has stated they are having issues, no doubt MTGox is still backlogged with tickets. Although if your ticket was closed, you might want to send magicaltux a PM with your specifics.
