Straight6 sent the wrong parts and would not take them back California Internet

I was told this company could supply a used piston for my 1968 Jaguar. They also said they had tail-lights in perfect condition. When the items arrived, the taillights had severe pitting of the chrome, and the piston was for the wrong engine. I had been very specific in my description, and had asked the vendor to verify the piston sizes and weights. He was incapable of doing this, or didn't want to.
He would not accept a return of the tailights, or send me the correct piston.
Other honest vendors later told me he is a known ripoff artist.
His name is Joel.
The company is somehere in California
