I learned the hard way to never call back and ask to be put on their DNC list or to talk to someone I could scream at.,All you do is confirm that they reached a legitimate number and they call constantly. Are you people sure it is adt? the perpetrator of the scam calling me has been identifying it as GE home security. IT must be a scam.Why would anyone buy a security system from a stranger who calls you? Why not call the ADT office closest to you?
