Happened to me, but with a tablet. They took pictures of a different brand tablet and said it was broken. I posted several photos showing they posted an LG tablet and I sold a Samsung tablet, and eBay sided with them. I actually circled and highlighted the differences for the eBay rep.
Got back a box of rocks and had to paid shipping. Ended up out $400.
I try to sell on here now as I assume regulars aren't scammers, or it's at least safer.
I sent someone a pair of Oakley Lenses once they swore they just knew were fakes. I had bought them from the NYC store so I know they weren't. Eventually ebay just refunded him out of their pocket.
Was weird though. He refused to take them to the store to get looked at.
