My first contact with the seller was polite and he duly refunded me.
Subsequently he has emailed me several times complaining about your attitude He describes you as 'your fearless leader'
That said, he claimed he had refunded you also.

He says that if any members ever bid on his auctions again he will cancel the bids

All that said, he did not even know your real name. I presume you do know he sells on ebay under a false name (Kim Stewart) and his real name is Ron Huber.
