ADT's service person was knowledgeable and efficient. Large order, he had to come back to finish. Checked in with me, long distance, when finished. Service center is great about checking in when a question arises. I don't go for a lot of bells and whistles, easy to understand and operate.
The tech who came out to install it was extremely knowledgeable and made sure I knew how to use the system properly before I left. He was great to deal with, and the whole experience was very positive!
I have never received such poor service from a company. They installed near 3 weeks ago and have yet to install the 5 cameras they were supposed to (2 of which I paid for). I was sold on the initial package and then ended up paying $1,000 more for "upgrades" that never even came. Now when I try to cancel, I get hung up on because I won't settle for the "you have to pay the rest of your 36-month contract out as a early cancellation fee" bull crap.
