Vivint installed defective equipment in my house and would never make it right. They put me under a two year contract and after being with them for 4 years, I was moving and needed to cancel. Vivint tried to hit me with a 700 early termination fee and claimed I renewed my contract with them. Every representative I spoke to on the phone was completely nasty, sarcastic and basically laughed at my demise. I commented on their facebook page about their unethical practices for 2 days in a row and as of this past week, they deleted all of my comments and blocked me from being able to comment on their page.
