Wrote in support.
It's been 42 hours.
I did not receive a response, but my coins arrived later.
Then it seemed suspicious to me, but I decided to use their service again.
This time my coins did not arrive at any of their BTC addresses.
Wrote here, in the hope that support will pay attention to my problem.
That is very suspicious sequence of events Imo.
Aynway, I hope PrivCoin's support will help you solve this problem.
From my point of view - they are trust worthy, but I haven't used them and can't tell for sure
