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?

Buyers cannot Cancel. They can only Request a Cancellation. You can Accept or Decline. Only Business Sellers have to accept as they have to Offer a 30 day Change of Mind Policy.

This was the first time I'd had such a problem; the advice given was very helpful in deciding how to resolve the matter. Many Thanks!
