says it's american security wanting to put a sign in my yard

American Security has called me from various numbers, w/various gimmicks designed to result in the purchase of their system, most recently, placing a sign on my yard. Each time, I wait until they clearly identify themselves, then inform.of "do not call number." I am assured I will not be called again. 4 months later the calls continue at all hours.
