Do not use ADT for home security in the Jacksonville area. You will, in fact, be working with Defender. There is very little communication between ADT and Defender. One hand does not know what the other is doing, so if you need customer support, you are passed back and forth between the two with zero results. This is the most amateur, unprofessional company I have ever had the displeasure of experiencing. When I first moved here, I was made an offer for monthly service. At my first bill, I was overcharged. A phone rep said that the error would be fixed and I would be credited for the correct amount. This was in August '17. When I was again overcharged, a technician came to my home with an updated contract in September. This was never processed as I was overcharged again. After several unanswered attempts by email to communicate my situation, as I wanted all future communication in writing, I eventually got another technician to my house in November with an updated contract, and I have continued to be overcharged. After using Twitter to voice my frustratuon, an ADT rep from their Indianapolis location got in touch with me in December and mailed me yet another updated contract. I signed and returned it promptly. Today I checked my bank account and...overcharged. Be smart and avoid Defender/ADT. I haven't even mentioned the inefficient, unqualified Technician who has made repeat visits to my house. read more
