tech related No show tried to steal my money los angeles, Internet

Chase- the owner and one man show of this company- came to my home to install a home theater system.  I read the reviews on yelp...  Big mistake.  This guy has no technical skill, is a liar who wouldn't answer his phone and was more than willing to take my payment but not do the work.  Luckily I used amex and had the charge reversed.  He kept dodging my calls until the charge was reversed.  I had to call from other peoples phones just to get him on the line.  In the end he never did the work, cut a huge whole in my wall and is threatening to sue me if I don't pay him for work he didn't do.

The real ripoff here is Chase from tech related but I think that yelp really let me down.  I'll be looking businesses over on this report before using them.
