I've experienced this before as a seller too. It's the worst. You were lucky you sold it as parts/not working! Don't give them a cent.

Funnily enough, the only bad experience I've ever had as an eBay seller was when I sold a Master Control Panel 5500. I had been using it for over a year, so knew it was fully working and I wrapped it like a baby (as I always do wrap anything I ship).

Well the buyer complained that it arrived damaged and wasn't fully working, but he said he had no camera to send me photos of the damage and it then transpired that it he was using it with a Beomaster 7000 but before I could respond, he left me negative feedback.

Subsequently he agreed to remove the feedback if I gave him half his money back but I thought about it and then wrote him a long and polite email telling him exactly what I thought of him and explaining he would be getting no money back. I also responded to his feedback so people could publically see he was a chancer. My 100% rating dropped to 99.9% for a few months but eventually returned to 100% and his comment was soon lost in my feedback history.

MrRoast - one very important thing to do is to add this buyer to your blocked bidder list so he can't do this to you again!
