DON'T TRUST ADT!!

I am so frustrated, I don't know where to turn. After paying a deposit of R7000 for ADT to install my alarm, they took 3 months to do so, after many, many fights, me having to put in day's leave, them just not pitching up. They apparently completed installation with my domestic (great!). Then without my permission, just debited my account for the other R7000. The alarm was never signed off and tested by us. It is still not working properly. I called last week to book another appointment with them. Was even willing to pay the call out fee. Appointment was booked for today at 15h30. They then supposedly got the appointment date wrong. When i complained, they said they would send someone at 17h00. I made sure i was home in time. At 17h30 they phone to say the guy is running late, will be here at 19h00. At 19h30 I phone, he pitches up at 19h50. Now he wants to test my alarm??? I have neighbours...So we had to send him away. I am so frustrated that i don't want them or trust them in my house. I want to get an independent person to install my alarm properly the way it was supposed to be (for the money i paid ADT already) and that they pay the independent person as they are useless, ************* and full of stories.
