Bad service

We are current clients of ADT and we had a PIR (added to a workshed) and LED light installed and linked to our current alarm system. It took me numerous calls and 2 weeks to get an installation date on the 24th November 2017. When my husband got home we realized that the PIR was making a noise at the control box inside (the technician didn't test this). I called ADT and they were not able to assist me. I have been phoning everyday since Monday morning the 27th November to get a technician out to fix the problem. Everyone I speak to says they will call me back. It is now Wednesday the 29th and no-one had called me. I have just called ADT again and they have no date booked for this.

I emailed ADT's complaints and I have not had a response from them either.

I am very disappointed with the service that I have received from ADT.
