So this week I bid on an item on eBay. As it transpired I was the only bidder on the item and I won the action. I promptly paid and expected it would be shipped soon. I just signed in to check my account and I have a message from the seller saying that they had to cancel the order as there must have been a glitch in the system and they already sold the item weeks ago. Now the listing no longer exists and there is no trace that I ever bid for it or won it except in this message from the seller. To me this seems more than a little dodgy. I cant see how an international company like eBay would have glitches in the system that would allow an item that had been sold to be relisted again? To me it seems the seller either didn't have the item or that they just didn't want to part with it for the low amount I won it at. The seller has refunded my money but this all just seems really weird. Where I stand with this? Is the seller allowed to do this? Are eBay at fault here? I just don't understand it at all.
