I get calls often and when I ask to remove my number, the caller hangs up. The recording states they are calling to lower interest rates on my charge cards.
This is a Scam & these are Criminals
They want you to give them your credit card #
Not to help lower rate but to use your CC # to buy stuff
FYI
Alway Alway always
Call your cc company or bank directly
Never talk to a bank or cc company that calls you
Hang up & call the number on the back of your card
