Called twice without leaving a message. Phone number indicated on Caller ID is unknown.

Keep getting calls from this number 1-331-800-3217 and the message is
recorded.  They claim to be a company who can get you a better rate on your
current credit cards.  They leave a number you can call to get in touch with
this service.  I never have and I am sure it is a way to get your personal
information.
