Hello, I sold a lounge set yesterday. Relatively smooth transaction until the person took the items and then realised it was too big for his unit and he wouldn’t be able to get it in the lifts or stairs. He called and said he wanted a refund and would be coming back with the lounge set to discuss. We said unfortunately we are unable to accept as we had purchased a replacement set already. He was insisting that he has now lost money because this couch is useless to him. He hung around trying to convince us to give him his money back and then it changed to some of his money back to compensate for his loss etc we refused and explained our side. He eventually left, very unhappy. My question is, is he entitled to a refund in this case? He told us to try to resell it, but as far as we’re concerned it’s his property now and he should have done is due diligence before making the purchase. Im sure any other seller wouldn’t even take the time to discuss this issue as it should be done and dusted. Please advise. Thank you.
