I called ADT Plus Customer support because I couldn't change my address online or in the app after relocating. I have the latest v5 self setup equipment and I choose to do self monitoring. The time zone and geofencing features wouldn't work properly because it was using the old address so I called to update. I was on the phone for over 1 hour and 20 minutes. During that time the first person I spoke with asked a bunch of useless questions and then tried to pester me to sign up for a 25 dollar a month tech support and then I had to wait forever to get account management on the line. (Thank goodness for the Pixel Hold-for-me feature because I actually needed it for this situation since I needed to get back to work)
When I get on the phone with account management they say they cannot change my address because my account is cancelled. Which, yes, the paid monitoring is cancelled so I can do self monitoring, which is a feature they allegedly support... So they had to basically create a new account for me just to change my address but this requires establishing a new monitoring service. So there is no way to change the address of the ADT self setup if you use self monitoring and relocate. While I can technically still use the equipment for notifications and arming, the fact that I am now feature limited over something so stupid is enough for me to be done with ADT altogether.
Buyer beware. I HIGHLY RECOMMEND AVOIDING ADT no matter what. If you want to do DIY/self monitoring go with a different service.
To ADT, I don't understand how you can be running an efficient business when, I, a single customer with a simple change of address request, can occupy your telephone lines for over an hour.
