I've had 2 transactions with him, both terrible. In the first, I ordered a pair of pants from him & his measurements were way off. The waist was a full 2" under what he listed. When I emailed & asked for return instructions, he replied by telling me that I had received exactly the pair of pants I'd bid on & that I couldn't return the pants. Assuming he misunderstood me, I replied by indicating that the measurements he posted were incorrect, and even provided a picture demonstrating this fact, but he still refused to take them back. In the end, I had to file a claim with Paypal--along the way, he was rude & curt at every turn.
Then, last year, I bid on a pair of shoes he had for sale. I won the auction and paid immediately. I received no response, & emailed a few days after paying asking if the shoes had been shipped. He responded by telling me that the shoes were "no longer available for sale" and that I could put my payment towards another purchase. I explained that I wanted the shoes I bid on and won, but he kept saying that they were "no longer available for sale." I suspect (but don't know for sure) that he sold them to someone else. The kicker here is that after he finally refunded my payment, he opened an Unpaid Item case against me.
