Deceptive illegal practices by ADT, no regard for customers

I signed on 3 years ago for a 36 month contract. I have dutifully paid for 36 months. Now that I have told them I want to stop their services, they say that I actually signed on for 39 months! A complete and utter deception. This is deceptive and illegal practice. I even have paperwork that says 36 months!!!
Second problem is the alarm system keeps beeping every day even if the alarm is not set to arm. I have to disarm it every single time it beeps. There is something wrong with the system obviously. This company has refused to fix the problem. They said they will someone to come fix it only if I pay them to!! Can you believe this nonsense?
I will report them to the better business bureau and I will launch legal action for illegal deceptive practices.

Great customer experience

I called ADT for my second alarm/cameras system for my new home in downtown Toronto and one for my cottage in Fenlon Falls. The sales rep that came to visit was extremely professional and knowledgeable about the cameras and alarm system. I highly recommend ADT.

First Review


Home Security

Read all the fine print, and make sure you ask around to see what your neighbours received. Locked into a 3 year contact, tons of billing issues for the first few months, sensors keep falling off, definitely not enough for the house, and to upgrade it would cost several hundreds of dollars. To get better home monitoring, would need to pay an arm and a leg. This wasn't worth it in my opinion.
