I bought a pair of shoes off eBay which didn't fit me. They were brand new and had literally been tried on once. I then sold them on to someone else. This person has now contacted me to tell me that they've fallen apart and that I have to refund their money as I mislead them in the listing. This isn't true - they were new and I sold them as such.
Are they right about the refund? I didn't actually MAKE the damn things, so is it my fault they've broken? Does anyone know what the rules are on this?
