Consumer Credit Card Services - Offer to lower my interest rates.

Thanks Jeff,
This number called me also about 10 minutes ago. I did not answer.

CALLED MY CELLPHONE NO MESSAGE CALL BACK TO NUMBER AND IT GIVES FAST BUSY

Looks like they needed a new number.  People catch on to them eventually and stop answering.  This is such an old scam it's a wonder it still works in favor of the scammers.
