I decided to go with ADT for my home security system in Aug. of 2011. BIG MISTAKE! First of all, the installer did a lousy job. Couldn't find the telephone line?? so he had to install it wirelessly....added cost, of course. Then, he screwed screws into my plaster walls and broke off pieces of plaster and left the residue all over the floor. He didn't give a damn that he was wrecking the walls. What kind of installer screws into plaster without drilling first for a plug insertion? Had to pay over $200 for the hardware and then $47 per month for monitoring. It took them over 4 months to figure out the billing for the monitoring fee. Never heard from them for months. Finally, in January of 2012 I got my first bill for monitoring.... $46.32. So, what happened to the previous 4 months....they had no idea. Then I realize that they have changed (SOLD) my Canadian account to Protect Your Home in Indianapolis, Indiana. Why? Just because. They tell me that only 5% of Canadian ADT customers' accounts are in the U.S. So, I have to call (toll free) every month to pay the monitoring fee over the phone. Or, I could simply give them my credit card number and it would come off automatically? I DON'T THINK SO. I was promised repeatedly, that it was only going to be a matter of time before my account would be in Canada. At the set up, and initial payment, I gave the installer a void cheque so that my monitoring could be automatically taken from my bank account in Toronto. That was part of the deal. Well, that never happened, and without any communication to me, my account was moved to the United States, in Indiana. What kind of disgusting customer service is that! So then, I was told that by July of 2012 my account would be relocated back to Canada. Didn't happen. Then I was told it would be done shortly after that. Didn't happen. It is now 3 months away from July 2013, and it hasn't happened. I'm sick and tired of this non stop nonsense from them. I know it isn't going to happen. And I am not prepared to call every 30 days to pay my monitoring fee. That is ridiculous. Then, about 5 months ago, my son who doesn't live with me accidentally came in and set off the alarm. While the siren was blasting, he called me at work and asked what to do. I told him not to worry, that the house phone would ring in a minute or so, and if he tells them the secret word, they will shut it off. After 5 minutes, he called me back, ..... no phone call from ADT. So, I gave him the passcode for the key panel and he disarmed it. STILL NO CALL FROM ADT!! When I got home, hours later, I called ADT to complain that no call was made to my house with the alarm going off. They made some lame excuse that it was disarmed 2.5 minutes after it went off. That was absolutely not true. And to add my last piece of complaint, I have approximately 8 different phone numbers that were given to me from ADT to call if I have an issue. Eight!?? And whichever one I call they tell me to call a different number. That is absolute nonsense. I am now totally fed up with the whole thing. I called ADT and the monitoring company in the U.S. to cancel the service immediately and got a new system put in from another company, and disconnected the whole ADT system. This kind of service, and selling Canadian accounts to an American monitoring company is disgraceful. Beware of ADT home security systems from whatever branch of ADT you might consider. I see there are like 20 of them listed all with different addresses and phone numbers.
