Got a call from them today. Blocked.

These as#h$les keep calling my cell phone.  It is a recorded call.  I do not know how to block them.  Is there some form of legal action I can take.  I am so frustrated with this, (at least 10 unwanted such calls, often during dinner, in the last week, alone), that all of the actions I can think of involve violence and would wind me up in jail.

Man on the phone left message saying "The son of a New York mob boss has given Islamic State a stark warning, saying if they are planning any attacks in the US, they will have to contend with the Sicilian mafia. The notorious crime syndicate say they want to do their bit to protect Americans. Giovanni Gambino, the son of a key figure in the Gambino mob organization, says the mafia is in a much better position than security bodies, such as the FBI or Homeland Security, to give Americans the protection they need. Now we know the Mafia is stronger than the US government."

WTF?

Called back from a blocked office line and it said "The survey you are reaching is now closed", but it doesn't say who they are.  It gave me the option to unsubscribe by pressing 9, but since I was calling from a blocked number, I didn't bother.  I didn't want to call back from my cell phone & confirm the number.  Blocked them on my phone.
