I have been having a similar issue, they were supposed to mail me a check and I had to directly email them to get a tracking number.  It has been 2 months and still nothing in the mail.  The tracking said "Addressee unknown".  The parcel gets mailed back and forth from my city to Georgia (about 7 times by now).  This is the only piece of mail the local post office has had trouble delivering.  I am beginning to suspect camp BX is up to something because I called the USPS and they said on the phone that there were some vital pieces of information missing from the tracking file.  It would be their tactic of proving that they "sent out the mail" with tracking but they have no intention of actually providing any check delivery in a way that would place the blame on the local the post office. 

How many people had trouble getting a check from Camp BX?
