Interesting situation - I sold a pair of jeans to a guy last week. He asked a bunch of questions, I answered, he put in a BO and I accepted.
They were delivered this morning, a few hours later, he gives me positive feedback. Then this afternoon, I get two messages in quick succession, first one saying "I knew this was too good to be true," and saying how the standard inseam on these jeans was 34 and these are 31, and asking if they'd been altered. Then a few minutes later, I get a message saying that he's demanding a refund saying that everyone knows these jeans come with a 34 inch inseam, and saying that clearly I was selling them so cheap because I was hiding the fact that they were altered.
Meanwhile, in the item description I clearly list the measurements (as 30.5), both in the drop-down box and below where I can type them in.
What's my liability here? He's already left me positive feedback, so I guess that's not a concern, and I agreed to give him a refund less 10% restocking as is my policy. Can he still open a case? How badly is this going to backfire on me?
From my experience you are fine. If you want t offer him a refund as thats your policy then thats all you have to do. He cant change the feedback, if he opens a case, call ebay and explain the situation and you should win if you in fact listed the correct measurement and he confirmed it via ebay messages. Add him to your blocked bidder list (and ebay black list) and thats about it.
