keeps calling, doesn't leave a message

I have been getting calls for a month.  I don't answer, they don't leave a message.  My number is on the DNC list and is unlisted as well.  Very annoying.  How to make them stop??

Daily calls around noon. I recognize the number and just pick up and immediately hang up now, but it doesn't seem to stop them.

It is illegal. My number is unpublished and I am receiving these calls.  I looked up the laws and they have to have caller ID activated if it is a solicitation call.
