I bought an item, it arrived, had been advertised as a different size to size on label so returned (at my own cost). Sat in the inpost locker for a few days so I sent the seller a message to check if they had collected. They confirmed they would collect that day.
Item wasn't collected and is now on its way back to me, what happens next??
The real kicker is the seller already has the item back up on their page to resell? Surely if you were that desperate to flog you'd collect the item?
