The 'credit card interest rate reducers' called me, and not recognizing the #, I answered. WRONG MOVE!!. It's the same recorded message w/,as far as I can tell, the same female voice as the other credit card scams. Putting it on my DO NOT ANSWER list
I'm also on the do not call registry and have been since I got my number 6 years ago; its also unlisted. I got a call from this number did not answer and called back. It was a recording. Put on your blocked call list.
