Barrett's Automotive and Safety Service

Barrett's Automotive and Safety Service LLC at 2695 so. 900 E. Salt Lake City 84106 took in my truck to do a safety emissions test and diagnostic for $118, then he went on to make unauthorized repairs on it stacking up to 3000 dollars. He then demanded $400 in cash only to get my truck back. I could not but could afford to pay him what was really agreed upon. He is holding my truck hostage racking up storage fees and what not daily. He called me the other day to offer me a deal of giving him $1000 to let go of it. It always changes. I will probably lose my truck by having to sign over the title at some point. Please help. There are many online that have said he has done similiar to them.
