I never have...
Well, that was just the short story above.
After he refunded my $$, I left him negative feedback saying he renigged on the deal. He then turned around and left me a negative feedback saying that he refunded my money and sent out the item...
Today, I get an e-mail from e-gay saying that the seller had filed a non-payment against me. I had already disputed the negative feedback with e-gay by providing information of my payment, etc.... Now I have to re-send my payment information.... Obviously e-bay has better things to do than deal with my complaint, so I just figured I'd set up a fake account and start hammering this guy with negative feedback...
