Who called from 7243020385

I received a call from 724-302-0385. They did not leave a message. Who is this?

It is CRF...Cancer Research Foundation

I receive these calls several times a week.   I finally called this number back.  Identified themselves as Tonya from Children's Dream Network.  I am on the Do Not Call List.  Told them I would take legal action.  Phone is in Aliquippa, PA.

SEVERAL TIMES A DAY SINCE 9/4/13

When I called, I asked them to take me off their call list. They said, as a charity, they are exempt from the Do Not Call restrictions....
