fraud or scam? LOL How on earth do you get to that conclusion?
It is no fault of the buyer if eBay decide to refund before return
As I said, as a business seller the buyer only has to make it available for collection
If the buyer had said the item had not arrived and claimed his money back, then I *might* but only a little bit, have agreed it was fraud on some small scale
It's subjective though, what has been acceptable to all you're other customers is not to this one, therefore you must accept the cancellation of the order and, in this case, collect it too
