Just be nice, take it back (IF it was received in the same condition sent..beware of switchers) and then block them. I just had a case..brand new 100 Mickeys Disney watch, new in tin, never worn, original price $95, sold for $28..buyer gets it and says she bought it for a gift and son didn't want it, so she's sending it back. What? Didn't know change of mind was valid, but OK, send it back for refund. Guess I blocked her too soon because she couln't get me through Ebay (but did get my email a different way to ask for my address....which was right there on the package, but oh well) so she opens a CASE..ridiculous. And naturally, since her reason to send back is not valid, she opens it as 'not as described'..so I Replied to case explaining a little more fully, but still saying I had offered a refund and will give her one after item returned. They will pretty much always side with buyer, so you just need to suck it up and take it back.
