Hi Michael,I know what your going through,this is what I did,when it happened to me.
Saved all emails(wich were'nt all that many)
Tracked down his phone number(wich he fused to give)
Tracked down his place of work,to try and contact him.
Saved and printed off all emails and tracking information.5 copys of each,1 for the FCC,The ARRL,His local PD,MY local PD,and his local Ham group.
Contacted and emailed eveyone in his local Ham Group(it was 1 of the local Ham guys there that suplied me with all the email addresses

)
In the End I did get my Alinco DJ-2000T back,with no manual+duty fees,so I did get the radio back with a little preasure,cost me $78 not including long distance calls from here(Ontario Canada) to (Frackville PA)better than losing a $800CDN radio though.
I wish you all the luck in getting whats owed to you,and keep the preasure on the scammers,someday and hopfully soon they all might go back to the rock they crawled out from under.good luck
