ADT refused to pay for the service charge to come out and look at the keypad they modified exactly five months ago. Until ADT "upgraded" the keypad I never had a problem with failed communications tests. Their response to me was that I should have initiated a service call sooner. Please remember that ADT was already aware of the problem as they called to report the problem to me every month.
Most quotes I got were around the 900 mark plus the 300 or so a year for maintenance and monitoring costs. The ADT package I got was around 25/month which includes 2 service visits and full monitoring.
I purchased a medical alert system after my mother fell a few months ago and it saved her life. I couldn??t be happier with the company we chose or the promptness of their response. I think every parent and grandparent living alone should have one of these and ADT is the right one!
