missed call no message lefted

Called ID shows "Tennessee Security". Left no message.

No caller ID, left no message

Called ID shows "Tennessee Security". Left no message... called number back and gave an option to press 9 to have your number added to the do not call list...

They called, no message left, I would never call these type of people back and never press a number they tell you, to be removed from their list or not, this could re-direct you to a long distance number you'll probably have to pay for. That's how these scammers make money. If the call is someone you know  or you called and know they number, pressing a number on your key pad would probably be ok.
