I have had an account with ADT for over 25 years. I recently moved to the Scottsdale area and they called a company called defenders, Inc., DBA protect your home. They are based out of Cincinnati Ohio. Do not have ADT install an alarm service in your home if they are using this company this company is threatening incompetent insufficient and should be reported to the Better Business Bureau. I cancel service and will never be with ADT again because of the harassing phone calls five times a day for payment that was one day late. That payment was One day late in their error not mine. Run and find someone else. Save yourself the headache. I'm only giving one star because I can't give a negative star. They don't deserve the one
