Who called from 2032221472

I got a call from this number and they said they were a home security company and they were going to give me a free system.

calls not solicited

I did not accept the call, it went to voicemail.  It was an automated recording that ended "...press 1 if you're willing to put a small sign in your front yard"  then the voice changed "or press 2 to place you on our do not call list"

This number calls my house at least 5x week and Im sick of it!  I'm not sure what to do,but if anyone has suggestions
I would appreciate it.

Thanks
