I sold an item cash on collection. Hubby was there when they picked it up and transaction went fine, she checked it over and left. Gets home and says item isn't in good condition, there is something broke and can't be used. I forgot it was broke but don't feel that makes it unusable. I offer a full refund but she isnt happy and asks to resolve another way?! I think she is angling for petrol money or something?ive just said no I'm happy to give you the refund but that's it. Would eBay give her travel expenses out of my pocket?! What should I do
