They call 3-4 times a day. I was bored and answered a call last week. They claim to be ADT. I played dumb for a time, telling them how I already have ADT. They were able to see I was a valued customer for over 10years, and I could get the free updated version!! Amazing I told her we have been using them for 14 years, that is over 10. Blab Blab....ADT
