Some garbage message about security.

This is for a security system which would be free if you allow a small sign placed in yard.  They said they have a no further call option by pressing 9.

I keep getting repeated calls from this number about "the FBI reports... Blah blah... Home break-ins...". I am on the don not call list and can't get them to stop.

Received call today, did not answer

Recorded message that talks about the FBI and breakins to your home.  They want to put a sign in my yard if to install a security system in my home "for free".  

Not interested, how do i get off the list?  I'm on the dnc list- can I sue these people for continuing to call over and over?  

Caller ID had the same number as their number listed.
