ADT - Poor customer service & no contact with the customer
Last month a part stoped working on my intruder alarm.
I have been waiting 7 + weeks for a replacement part now.
Its a brake glass sensor.
Available and in stock at various suppliers I have located.
The part is sitting on a desk after being taken off the wall by the ADT engineer.
If your unable to locate a common part - Call me updated me or substitute a different item.
Don't leave me wondering if something might be happening!
The worst part, my alarm has been compromised for a few months now not working to the full extent of the equipment installed!
The service I am receiving is shocking!

Upgrade installation
Sorry to say since writing the review. The system will not work correctly and any interaction sets the siren off. It seems that i was not told how to arm/disarm correctly after it working correctly for a few days. Awaiting an engineer's visit.
The upgrade installation was completed quickly and efficiently. The instruction leaflet could have been more informative but a quick Internet search answered the questions.
