Signed on with ADT in 2014, there were constant issues of false alarms including receiving 5 am phone calls from ADT while we were travelling; we then sent friends to look at our house and nothing had happened. I received a letter from ADT cancelling my service for system issues - once again faulty ADT equipment. Because it was a break of contract, they are saying that I have to pay the cancellation fee even though it was ADT who broke the contract. Bunch of con artists hiding in a corporation.

This company's left hand doesn't know what it's right hand is doing. They messed so much up that they gave me a 6 month credit, which they have now messed up and I haven't received despite a couple a months of phone calls, fails to follow up on calls back, and totally unhelpful people on the phone. Despite a great deal of patience, they have shown no interest in making things right or following through on what they say they will do. So many lost hours and frustrations.

I alarm service with reliance protectron and signed a 5 year service contract in 2012. In 2014 adt purchased protectron. I didn't sign a new service agreement with adt, or authorize adt to continue service promised by reliant. Adt is now coming after me for balance of a contract that was signed with a completely different company. Not Happy!!

I am very disappointed in the alarm installation and follow up service (or lack there of) from ADT. The previous alarm was ripped out unnecessarily causing willful damage to the previous contractors equipment. In addition, when I called to ask about this or about the contract no one will return my calls after several attempts. Do not go with ADT.

I got invoiced over 2 years ago for a service they couldn't provide (installation problems) but kept on billing me eventhough i cancelled the damn services from day ZERO. it's over 2 years and ADT's accounting department cannot seem to get it right. I just got an invoice today that states it is 619 days overdue!!! I would never recommend this company to anyone i know. Even my maintenance team was wanting to change the security monitoring from Chubb to ADT and because i look after the area, i would not approve. Sorry ADT, you lost a big contract with me and the company! All this trouble for $400.00. i think i have wasted over $400 in my time and should be billing them back!

Our house was broken into when we were on vacation. ADT was quick to respond to our request. Very effecient. Easy to operate alarm. Have peace of mind and secure feeling whenever we are not home.

Shane took hours longer than expected, took personal calls, forgot all his equipment and then told me he was going to take a break! I was very disappointed. The sales lady was awesome and the overall company service was good. This installer was not.
