Be Afraid! Be very afraid. While this company uses the ADT logo, they are not ADT. We purchased an expensive system in March. We told them we only have Verizon in our area. They said they would install with a Verizon card. We now learned six months later our system has AT&T and not Verizon. We have not had security for six months while we believed we did. We have run into a wall with ADT who now says "too bad, you dealt with an authorized dealer not us." We can get a fix from ADT but cannot use our smart phones to monitor the security, which is precisely what we wanted in the first place. It is a shell game! We are locked into a two year contract and own the wrong equipment. Customer service has been terrible, ADT has all their answers to eliminate any their responsibility. Caveat Emptor! read more
