if I could give ADT minus stars I would we’ve had four years of poor installs terrible service. It’s very clear ADT want to charge the most and cut their costs to the minimum. We’ve had cables for cameras running in gutters. Even though you pay for servicing they no longer come out they don’t change the batteries in sensors to cut their costs. when your system does go into fault. They’re well aware and their only aim is for you to take responsibility and delay any engineer. I suspect they’ve got very few engineers left their as fed up as the customers. to be honest, the only reason for giving one stars is when the engineers do turn up and you can get one, they usually good guys, but fed up Don’t bother using the ADT app because all that does even if you request an engineer and say which day you’ll be on site is delay it and they will just call you to triage on that day rather sending an engineer. even though they were aware the system has multiple faults is completely dead, there was battery low warnings they’re all well aware of it all but they’ll do nothing until you call even though you’ve put all the details through on the app. as you’re fed up with phoning them because you wait half an hour for someone to answer the phone and then it could be four or five hours before a telephone engineer. Will call you back Total terrible customer service all with the aim of minimising their costs if I could give 0 stars I would. ADT a accompany living off their reputation of 20 years ago.
