In my opinion, ADT Security has not provided the level of security service or administrative service they should. My experience with ADT Security has not provided me with a great deal of confidence in their service, or that they would actually provide the home security and medical emergency services that they claim to provide. They "mistakenly" actually cancelled my security service, then backtracked to claim that I had upgraded the service when I did not. Then they billed me twice "by mistake" once for almost $3,000 once and $700 a second time, when my payments are made automatically billed to my credit card and I have written proof that all payments were made in compliance with my ADT contract. All of this does not inspire confidence that I can depend on ADT for competent help in an actual home security or health emergency. Does anyone from ADT actually read these reviews? Is ADT going to wake up and provide the level of service they claim to? Does ADT actually care about anything besides taking your money from you? Extremely concerned and very disappointed ADT customer

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.

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.

Look elsewhere Look elsewhere! ADT adds unnecessary complexity at every opportunity. They have 3 different websites you have to deal with if you get both the alarm system and camera system. Then if you sign-up for the auto monthly payment and ever change your credit card, the system can't handle the change becasue it's two separate bills but it doesn't tell you that (unbelievable). It took me 5 days and a couple calls with their customer service who barely speak English to finally get it all sorted out. With today's technological capabilities this type of account credit card modification should take 1-2 minutes but with ADT it unfortunately takes days and a tremendous amount of frustration. Soooo unnecessary! Wish I had gone elsewhere.

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.
