So it's been 24 hours thus far and still no reasonable response.

BitInstant's idea of customer support is having a 150+ page thread with one representative?  I've tried to chat with representatives on your website, sent a support email through your website with no response, posted to this thread, and have personally PM'd Ursay.

Enough with the "check your confirmation email for a MTGox code" canned answers.

BitInstant has either been hacked or is grossly incompetent.  Either way they should not be dealing with money

As you can see from my transaction details below, my order had nothing to do with MTGox whatsoever.  The funds were sent to a personal bitcoin-qt address.

Stop blaming MTGox for a mistake that was clearly made by BitInstant.  Stop holding me hostage and forward on my funds.
