Time for feedback on car for sale

Yes...I sold a car and then the guy didn't pay. So I had the fees. SO I wrote to Ebay and complained. They allowed me to relist it and he was suspended. But the same guy changed his Ebay ID and did it to me again. In the end I had to pay a good bit and never got it resolved the second time. The same thing happened with a motorcycle. Ebay told me that we were both ebay members and they did not know who was up and up.
