Vivint did a system move for me and my family. After the "professional" said he was done I asked about my door locks. He said he didn't have them and I would have to have a return visit to have them installed. Well after calling for 1 week Vivint decided to disconnect my service and allow me out of my contract. But now they want me to pay a monthly fee since I didn't send them a notice of cancellation. I was never told I had to do so. This company is a joke and has horrible customer service at there corporate level.
