Why would someone not want their money back and want to go through more hassle and stress to wait for a "trade"? Stop facilitating more BS and just get your money back without the mind games.
IMO there is no need to be contacting his gf, or his mother, or whoever you find on myspace through your "detective" work. Youre just creating more unneeded BS for everyone involved. Just my 2 cents
"Detective work"
