Just so you know, I had the same problem as you guys but I got my BTC in finally.

I was seeing the same things as you guys are now: no response from anything: not on emails, not on the support channel, not on the PMs to URSAY, and forget about the phone. I was getting mad. Just relax a little bit and be nice.

To give you an idea of my situation:
My deposit was on 4/7, I eventually got on a ticket for 4/8, and I got my BTC at the current rate on 4/8.
I PM'd URSAY to escalate and get them to honor the exchange rate at the deposit time on 4/7. Now I'm waiting on that, and on a ticket for 4/9. FYI Yankee, the CEO of Bitinstant, came on the thread earlier and said himself they'd honor the exchange rate at the deposit time: https://bitcointalk.org/index.php?topic=128314.msg1776479#msg1776479

So yeah, just be patient, realize that their automated systems probably took a beating and theyre having to do things manually. Theres only so many of them (and yes theyve hired more people)

Just make sure you get URSAY to see your QuoteID and to get on a list
