ADT---A BIG LOAD OF *******

So tired of adt... We put an alarm system in a few months ago. First of all the guy they sent out named Paul to give us a quote didn't know anything... Tells us this outside beam will cover whole garden area... It doesn't. They tell us to put more beams in. We are often getting calls saying zone 16 or zone 18 is going off... We only have 8 zones. Constantly get calls saying alarm is going off when the alarm isn't armed... Like I have just received a call that my alarm is going off. I have been whole day and the alarm isn't going off. We keeping getting threatening calls from finance department for owing them money for installation... The system is *******. You owe us money for the constant time we have to come out and leave work for you guys to sort out system but is still not working!!! I've had to take a number of days off for this and still not resolved. We keep telling them they must get the main boss to phone us so we can speak to them.... Still waiting. Will never recommend your service to anyone. ABSOLUTE *******!!!!
