Ok so I listed some Chanel sunglasses for sale on eBay. I knew it was going to be a risky auction bc I have no paperwork, no case, nothing except the sunglasses. They ARE authentic though. I had 2 bids. 7 days, no payment, I open a dispute against the buyer, he indicates he's going to pay. Now he sends me a msg saying that he went to the Chanel store and they didn't have the sunglasses so he thinks they are not authentic. Well, of course they didn't have the sunglasses, the style is more than a year old. I don't know what in heck to do. I'm sick of dealing with this guy. Do I have any options?
