sorry not too good with links but go into Help and type Final Value Fee Credit, I seem to remember ebay will open a case in their Resolution Centre where they ask your buyer for the money, you give the buyer 14 days to pay and if they dont, then ask for your fee to be refunded. You can then go into Help and type Block Bidder. Type their ID name in so they cannot bid from you again. And give neg feedback. Looks like theynhave had it before. Then you can list again. Dont automatically relist as ebay will charge if you do not sell.
