Auto dialed call to my pvt cell #... went to voice mail.  The message was:  "...call from Card Member Services... offering to lower my rates on my existing credit card.  The problems at this point were threefold... 1. They needed me t provide them my credit card info (they didn't have it), 2. I don't have a credit card!  and 3. I am on the DNC list.  Given this... this is not at all likely to be a legit operation.  I classed them as a Prank call only because there is not a "likely scammer" category.
