Getting screwed over on a payment for a parts purchase?

I had a guy do me dirty on e-bay parts that were listed as new and were obviously used. he tried to game me out with the usual: I've been doing this for 30 years and you don't know **** spiel.

I wound up getting my money back after the whole debacle. but the guy was a total douche canoe about everything.

then he started spouting off on a forum about me, and how I had ripped him off and nobody should buy or sell with me.

wrong move. I had his name and address from shipping. a little google-fu dug up his place of work. a quick email to his work with some screen shots of his nasty messages to me thru e-bay and on that forum prompted a phone call from somebody higher up in his company asking for confirmation and more evidence of his malicious behavior.

he was shown the door over that. all for less than $200

and this wasn't some kid farting around. dude was in his 60's and a mid level manager at an international company.

so, what I'm saying is you have some recourse if you have a little information and a bit of spare time on your hands...
