quit calling my number, I am on a do not call list

I am on a DO NOT CALL LIST for withheld numbers, so please don't watse yours or my time calling blocked.

I'm on a do not call list also.  The company (?) witheld thier number for the call, fortunately with AT&T you can look up the number on your account history, it just doesn't show on your caller ID at the time of the call.

Called WITHHELD, No message,, so I blocked them.  Can't identify with a valid name and number don't call.

WHEN I ANSWERED SOME WOMEN ANSWERED I ASKED HER TO REMOVER MY CELL PHONE # FROM THE SYSTEM THEY SAID THEY COULD NOT. THEN SHE ASKED ME IF I WAS INTREEDED IN LOWERNING MY CREDIT CARD BALANCE. I ADVISED I DON'T HAVE A CREDIT CARD AND I DON'T WANT A CREDIT CARD AT THAT POINT SHE HUNG UP ON ME. THEY CALL JUST ABOUT EVRY DAY AS A PRIVATE CALL. THIS IS VERY ANNOYING

They called my number "unknown" so I did a reverse call back and it said that the number I called was not in service
