720-568-0551 / Live solicitor, for ADT security. Looks like I'll never buy an ADT security system my entire life time. If they can't respect the rule of law regarding no call lists, it's doubtful they'll fulfil their customer promises regarding other forms of security. Thank goodness for my Sentry 10,000 number call blocker I picked up on Amazon for only $40 bucks. That makes rejected number #53, in only a few months time. Call me once, and never call me again. Love my Sentry call blocker.
