I have been using campbx since November 2013. I have never sent in money order or checks, only bitcoins and ACH withdrawals. I must say that they have been almost punctual, two to three days when I withdraw fiat by ACH withdrawal. I will continue to use campbx, just not money orders or checks.
And I had the same experience since the beginning of September until 1 bitcoin wasn't retrieved by them. I watched the value of the coin in limbo go above $1000 and couldn't sell it.
