I have had an account for 6 years. I have been increasingly concerned about the communication for a few years now. Lately, I have not had a call to tell me my telephone line was out of action for 5 days, essentially my line to the data centre is not working and therefore my alarm is useless!!! I phoned ADT this evening to see if a sales person could call me tomorrow to arrange a review of my security products. They told me to phone back in the morning. In short; they take my money, offer little comfort and customer service seriously lacks. They have become too big for their boots!!! I have another quote from another company which I shall pursue.
