I called just to see what would come on the other end, and it is voice software that says "Welcome to our telefinancing services" and then schpiels something about "my" card being limited, and that I should press 1 if I want to re-activate.  I just let it sit for a bit, then it asked for "my" 16 digit card number.  Clearly bogus, with no company identifier etc.  I wonder how you turn this number over to proper authorities for investigation!
