From the posts above it looks like this is a Garcina Cambogia Scam! That is good enough for me. I am on the "Do not Call List" so they should not be calling me at all. Getting on the DNC list was a big help. I get a lot less calls now.
This is a one of those "this is your last chance to lower your interest on your credit card". They just called and left a message on my answering machine. Now I will add this area code to be blocked by my Digitone Call Block.
