I am currently having a similar issue with them at the moment. $1,000 in money orders (2 x $500) were deposited by them on 10/25 and were cashed by MoneyGram on 10/30. The money should have been credited to my account on the 10/29 (2 business days after the 10/25), but this has still not happened. According to the ticket replies, they cannot find the money orders in their bank records and therefore won't credit me the money - even though I have copies of the money orders with the deposit date, batch number, etc., showing that the deposit did occur. The money orders had everything necessary on them (username, name, address, etc.) in very legible handwriting as well.
At the moment, I am waiting for their bank (BofA) to do "research" to find the missing money orders. The problem is, according to various posts on this site, my case does not appear to be an isolated one, and that raises a huge red flag - bank deposits just don't disappear, even on an irregular basis, for the same bank customer.
