You mentioned that you deposited $5600.00 in his acount. Did you use Paypal?? Get them involved if you did. They surely have records and if they do nothing - whoa - maybe I'll be done with Paypal myself. Another suggestion someone else was to get ebay involved. Although good luck is in order when crap like this happens on ebay. I recently had a much smaller problem than you but still a problem with a seller on ebay and contacted them and arbitration and anything else that looked helpful on ebay. After 6 months they still haven't done a thing. Very dissappointing. Anyway, best of luck.
