HELP asap! Just bought a boost controller (think I got scammed)

Yeah I just got off the phone with turbo xs. I told them I was missing that part and asked if I could just purchase a new solenoid with the top adjustment but they said I couldn't cause they come assembled and pressure tested. So I'm assuming they don't even make these themselves. But anyway I messaged the guy I got it from and I told him that it's missing the parts and I would like my money back. We'll see how that goes..
