A salesman came out to my house last Saturday, ignored my no soliciting sign, and yelled at me for having an ADT sign in my yard, when my service wasn't hooked up. Yes, he was literally screaming at me. I had to kick him off of my property. When my husband came home, he asked where the sign was. The guy took it. Why does ADT think I would let some crazy, aggressive stranger into my home? I have Simply Safe, no aggressive salesman, no hassles, no high billing.
