I had the same kind of problem with a certain 71-73 vendor in Massachusetts a couple of years back. I too got the state attorney general involved. It took a while, but I eventually got my money back. I see from my monitoring of the parts for sale page that the guy hasn't gotten any smarter either. Good luck and be persistent.
