Purchased Vivint April 2019. I have glass break & motion sensors in the house. Doorbell camera. Garage door control. Thermostat control. I've had several false alarms. I have had issues with my doorbell camera. Repeated issues with the garage door controller. When I call Vivint I have to plan for an hour on the phone. Half of the time the problem does not get resolved to my satisfaction. Customer service says they will call me back. They don't. They're always polite but most of the time poorly trained to help with technical problems. Really quite terrible. Most recently the garage door controllers in both of my cars stopped functioning at the same time. They've been working fine since my system was installed. After an hour on the phone with Vivint I am told the controllers in my vehicles aren't supposed to be used for garage door control and that I should only be using my phone app or the Vivint control panel or the button inside my garage. Unfortunately I have purchased the Vivint equipment and they won't give a refund. I want to get rid of Vivint and I can drop their service, but then I'm stuck with their equipment. Such a bad situation!!!
