keeps calling every day and leaves no messages.

Calls every single  day and it comes right behind another number that calls and leaves no message.

Also I feel to see if anyone is at home. DO NOT pick them up,

Calls every day.  I have picked up and asked  not to be called again, but calls keep coming.  I have listed this number on DNotCall.gov, but calls keep coming.  How do I get rid of this annoyance?
