ADT was the worst... recently moved to Toronto and was setting up my alarm. Basically, the CO2 sensor was broken (brand new). So okay, after stopping the fire fighters from breaking my door with an axe, I thought it was faulty equipment, fine.
They were supposed to put the alarm on test mode so that it wouldnt alert the fire fighters until it was fixed. they scheduled a technician to visit... technician didn't bother to show. Guess what, test mode was off... I get a call at 3a saying fire fighters are going to break down my door... I rush over, JUST IN TIME! 2 seconds later and my door would have been done.
So a technician finally comes... he didn't bring a ladder!!!!!!!!! so i had to wait again, sure enough, the alarm goes off a 3rd time. Then they finally come and fix it.
The sales guy was great... but the follow through was SO horrible, I wanted to pull my hair out.
