Im on on a no call list, who are these people?

This number has called a family members home number several times a day/evening over the past couple of weeks. They give no response when the phone is answered and leave no message if the answering machine picks up. It is apparently a cell number in Falmouth, KY.

Getting a call from this number just about every day- no one is ever on the other end - it just hangs up. Tried calling the number back and a message says this number is not in service.  Very odd.

They called us several times, left no message. I answered tonight and a woman asked for Mr Burton, (not our last name) I told her wrong number and she said oh this must be Mrs Burton, again I said no, wrong number, and she said oh well we must have the name wrong but this is your lucky day you have won a complete home security system free, I hung up, we have been on the DNC list  for a few years I even updated our info last fall and all the calls stopped for a while, and now over the last few days the calls have started again.

This number keeps calling us too but no one is on the other line. Call back and get a message this phone number is not in service after 4 rings. Very odd.
