14 negative in a year and you bought from him? Not trying to be a buzz kill here, but you gotta check that stuff. Ebay does an awful lot to try and protect sellers - feedback is one of them. And really, what happened isn't Ebay's fault - it's the seller. You could have protected yourself by doing just a little more homework.
Irregardless, I hope things work out for you. Just remember, don't go cussing him out BEFORE you get your money back.
