I sold a fully working Smeg coffee machine in v good condition yesterday on market place. The buyer has today sent me a video saying it’s broken and asking me how to fix it etc. It does look broken in the video but it was one hundred percent working when it left here and now I don’t know what to do. I feel like he’s going to ask to return it but that would leave me totally out of pocket obviously. For all I know he dropped it on the floor when he got it home. All I do know is that it wasn’t broken when it left here 😭 What should I say?
