ADT Mississauga

Unfortunately ADT service has changed greatly in the past decade, for the worse. We have spent hours on the phone booking and rebooking service appointments. Service technicians are not properly trained and ill equipped to complete simple repairs, ie-reinstalling window sensors. We have wasted a great deal of time and have been left with only frustration with ADT "service". After 13years we have had to make a change in companies. Do not waste your time with ADT.
