The only help that could be offered, ONLY IF, the thread has not been deleted, is a possible copy of the thread. Anything done away from, or NOT posted on the forum, is your transaction, and YOURS alone.
That is another transaction that was not properly done, nor documented. PBNation ONLY offers a place to put the ad, they are in no way, resposible for, or to, either party involved.
I hope this answers any questions/concerns that you may have.
