Robo call to sell alarm system for your home.

It's a call for a home security system. Left a message when I did not pick up.

Robo call left message.  ADT home  security systems.  The recording tells you to press numbers according to who you want to speak to.  It doesn't recognize that the call has been picked up by a message machine.  I'm so tired of these kinds of calls now on my cell phone too.

they called. i picked up. they hung up on me after i asked "hello?"
