Ebay Buyer Issue - Please help?

Not much you can do except file a 'Non-paying bidder' claim with eBay. Do not voluntarily let the deadbeat out of it, make eBay let the deadbeat out of it and give him a NPB strike. Get enough strikes and eBay will suspend the buyer's account or close it. eBay will return all of the fees they charged you on the sale, but check your account to make sure they do.

Technically, you could sue the buyer, but you would have to sue them in the jurisdiction where they placed the bid, not where you live. Not worth the trouble, and if you did win, good luck collecting on the judgment.

This is a seller issue. The best thing to do would be to cancel the transaction and possibly block the buyer you had a hard time dealing with. Then, you will be free to put the phone up for auction again and if you blocked that buyer they wouldn't be able to win the auction again.

Contact eBay support and tell them. I am 99.9% sure that once a bid is made, there is no backing out. Either they will pay for the phone, and you will ship it, or eBay will reimburse you for the bid on the phone, they will take it, and try to make as much money back as possible.

I'm not sure, maybe contact eBay for help. Otherwise he may simply refund you and not send or just agree and let it go. He truly may have accidentally set the starting bid wrong. Who knows.
