So have i, I believe that they are robbers trying to figure out which house is equipped with an alarm system. If you do ask for a free sign, they will know where you live & that you do not have an alarm system. I told him that i already have an alarm system, and he asked is it was active or not. I said it was, he said bye & that was it. just hang up

ADT calling. When I asked to take me off their list, she said "That does not apply, this is not a sales call". Really annoyed.

Same here, my new number was just set up and I get calls from this number and ADT all day long. This is very irritating.
