I wish people would learn what a Bait and Switch is.
As for the seller he offered you 100% refund.
There are 3 possibilities-
1. He used a stock photo in the auction. You bitchr is with Ebay as they allow it and he offered you a refund.
2. He had more than one of these and sent you the wrong one by accident.
3. He out to screw people. If he did I would think that he would not have offered a refund.
