Deceptive practices. 2 Vivint Reps who were not identified in any way as Vivint reps, saw the ADP sign in the yard, knocked on my parents' door and said they were from the alarm company and needed to talk about my parents' renewal.
Told them they would upgrade the system for free - my parents (79 & 83) thought this was ADT who did a good job and never cheated them.
Vivint added some new contacts and charged them. Talked them into a new thermostat and charged them and they ended up with a monthly bill that was $20 more than they were paying ADT with a 3 year contract. The thermostat didn't work well - house would get to 60 and the heat wouldn't turn on even though it was set to 70.
Took many phone calls and talking to a supervisor twice before they finally took the thermostat off the monthly but my parents are stuck with the higher payment.
Nice sales strategy - go through an old neighborhood, find senior citizens with an alarm system, and trick them into wasting part of their small fixed income. I guess if you fail at selling crappy used cars you can go to work for Vivint.
