I have received numerous calls from this number.  When I pick up I get silence & then a hang up.
When I dialed the number I am told that this number is not in service.   DNC is useless, so how do I get them to stop calling

They have been calling at exactly 3:02pm EST every day for last week. No message, no one on the other line, and "not in service" when I call back.

Getting calls from all over the place, this is the last one in a long-long line.  No one there, not a valid number and this is insane.  DNC isn't doing anything - I've been on the list for several years and I "renew" it every 2 to 3 months.  I'm fed up with this!  My number's not even listed~~

Suggestions are most welcome to stop this bs!
