Signed up in 2011 or 2012. Once my contract was up i ran..... Very bad customer service. The people are great but they're limited in what they can do for the customer. Almost every call had to be escalated to floor sups who refuse to escalate to a manager. One of my calls went like this. "Oh your sensor maybe bad its covered under warranty but it will be $55 for the tech to come out". I have plenty of other bad experiences with Vivint. Trust me find another company. Please hear my words!
