ADT is awful when it comes to Costumer Service They are unbelievably slow and inefficient. Spend hours over the phone and all they could do was passing me from one department to another. It’s like they hired the least knowledgeable people with least experience and asked them to answer the phones. Their system definitely is inefficient and not working. Their security system might be good, but horrible costumer service experience I had. Even talked to several account managers and they also were the same, passing the hot potato to the next person.

ADT specializes in locking you into a plan and forgetting about you. Ever hearse of the term "lock in." it's what keeps companies like ADT in business. They're banking on the fact that when you spend so much to have one of these alarm systems installed, it's very difficult and expensive for you to switch to another provider, which means you'll generally remain a customer, no matter how bad the service is. And as others have noted, it is awful. They recently sent a freelance contractor out to replace the wireless system panel in the basement from 3G to a more up-to-date cell communication method. He botched it and a few days later, all the alarms started going off at once. I called ADT and they said they saw nothing wrong on their end and that they could send someone out in a few weeks to take a look. They could literally hear the alarms blaring in the background (the decibel level was horrific, and I had to go around and rip the wires from the units to silence them). Then I kept getting calls from an ADT system over and over saying that there appeared to be something wrong and to call them. A few weeks later a technician came and acknowledged that the guy had screwed up the installation. They redid it. Then recently I had a problem with one of the smoke detectors and a technician came and said I should order replacement batteries from ADT because I was on the free battery replacement plan. This had been the case for years (25 to be exact). But when I called ADT they said the plan did not cover batteries (which cost $18 apiece -- not exactly cheap). Previously, I had spoken to a customer service agent to set up the appointment, and they too said I was covered under the battery plan. So now two representatives from ADT have said I'm covered and one said I was not. How bad is ADT's computer system that you get such different answers? Also, when I do replace batteries myself, the alarm goes off but I don't hear anything from ADT. They used to call to make sure there wasn't a problem. Now, nothing. This company is horrible.

Can't spend hours on phone Had 2 window sensors triggering tamper alerts, or just going off inappropriately over several months. Police called once. Talked to support, set up virtual tech appt (won't send to house anymore, I guess). Virtual tech quickly agreed the sensors seemed faulty, ordered replacements and set up future appt to install and register in system. Helped me remove faulty sensors from system (unregistered them). Box arrives with just one sensor. Tried online chat, who couldn't help, gave me phone number to call, transferred 4 times, finally someone seemed to understand and ordered missing sensor. Box arrives with install kit, no sensor!! Another round of calls, got cut off once, second agent did not understand me at all, tried to help me troubleshoot, despite my telling him I've already had virtual tech appointment, etc. I had to hang up on him, he never got it at all. Now I have a future virtual tech appointment to install and register my one new wireless window sensor in my system, I'm hoping the virtual tech can order the missing sensor, then I'll have to have another virtual appointment to get it registered as well. I've already spent 60 min on the phone just trying to get the missing sensor. Not eager to try again. When I purchased system 19 years ago, promised in house service (which would have solved this in about 30 min weeks ago), but despite increasing fees, I guess that's no longer the policy. It sucks.

ADT is a terrible company ADT is a terrible company, my cameras never worked, I was paying a lot money just for alarm on my front door. Every time I was calling to see if someone can fix it they told me I have to pay $180 for the services and I have to buy another cameras or monitor. I canceled my membership more than 2 months before the expiration and they didn’t want canceled and continued charging me. I finally got rid of that but they still charge me $34.99 because they told me was not enough the time to cancel it. I’m not recommend this company to nobody because the only thing they are doing is charging more and more money. “Money Hungry “

worst company I have ever done business… worst company I have ever done business with. Through false alarms, alarms going off AFTER events to us attempting to get our CO and sell our house. The tech said it would be free of charge, they came here and tried to bill me. I told them I just need a review that my equipment is in working order to sell my house, after all I was a customer for 25 years. The tech called his manager who refused the service. Stay far away, you are better off keeping your doors wide open.
