Hi I sold a fairly expensive pair of speakers. The buyer has got back and (rather rudely) has said one has some distortion due to a damaged internal part. They were in perfect working condition before I boxed them up and sent them via courier. The buyer offered to send them back for a full refund but I am concerned that as he has taken them apart they will be returned damaged and unusable. I have offered £40 pounds as goodwill gesture but he is not happy and is threatening to open a case. I am not a regular seller could you tell me the consequences if Ebay found in his favour? Will they? Thanks.
