We've had ADT for over 10 years and want to cancel. Apparently, you have to cancel on the phone with a live human. After several long holds (20 minutes plus), I refuse to waste any more time waiting for the privilege of cancelling. While on hold, I googled "cancel ADT" and read a bunch of horror stories about how difficult ADT makes it to cancel their service. Has anyone had recent experience cancelling? What did you say/do?
