Caspian painter

I hired Caspian painting to paint the interior of our house. We wanted to do some renovations and put the house for sale. He gave a quote for the painting and I accepted. This was a rental house and I was in process of getting different quotes to renovate the bathrooms, install pot lights, change the floors, etc. One day I went there and I saw that Ali has started to rip off everything and he has brought an electrician, carpenter. I told him I did not contract the job to you. I just wanted to paint the inside of the house. So I hired someone else to paint the house. Later on, I found out he has put a lien on our house and also put claim in Smart Claim Court to get money from me. He is a con artist. He does this to get money from people.
