Does dry fogging remove mold from the house?

I had a company come over and do a mold inspection. We found some mold and were referred to a company in Kansas City MO called Pro Air mold remediation. It seems to have helped some but I am skeptical it works like he had described it. It was over three thousand dollars for his treatment. Did we get ripped off? https://pureairkc.com/ the web site does through red flags at me. I was desperate at the time. Living and working from my car. I am able to be in the house now though.
