Appalling customer service (wish I had read all the reviews here before using them). We asked for an Engineer to carry out repairs to our camera system. Was assured this was covered in my annual plan. 1st Engineer came out, scratched his head and asked why we didn't have a monitor? We were under the impression that our system didn't come with a monitor but he insisted that he had never seen our set up before - he was with us 15 mins and then left advising us to contact ADT. Contacted ADT, they said our system doesn't come with a monitor and they would send out a second engineer who came out and asked why we didn't have a monitor!! System is very badly set up under the stairs with all the usual stuff - coats, boots, vacuums etc. I had to clear all this out and dismantle my own work station for him to use my monitor! He did get it working again eventually. A week later we received a bill for £1050 for the Engineer call outs!!! Phoned accounts dept, they told me that the bill was correct. Put in detailed complaint to customer services and they apologised to say this was an error. All sorted......or so I thought....just received a bill for the next 3 months despite twice having told them we had cancelled. Still fighting this one. I have never seen such a badly organised company. Their products are shoddy (the app is rubbish) and their communications are terrible. I don't know what I have been paying for for the past 3 years.
