Winning Bid cancelled, what do I do?

[gourmont]

My buyer cancelled their winning bid, saying they changed their mind. The item is now in my selling page, sale completed, waiting further action. I got through to an expert seller who directed me to the Second Chance option, which I took. But the original sale is still there! What do I do to cancel the first, unpaid transaction?

A buyer cannot cancel unless by opening a request to Cancel case and only with your agreement as a Private seller...  See >

If you have not been paid ? > unless you open an Unpaid case/s and return to the Resolution Centre to close it as still unpaid 5 days later to recover your selling fees, eBay will expect those fees to be paid ... neither party can leave damaging Feedback and any left during the case process can be removed on request  ... you can then safely relist >

Cancelling the sale is risky, only lets them away with non payment and still leaves the timewasting 'buyer'  with the option to leave damaging Neutral/Negative Feedback for you >
