Keeps calling and hanging up when I answer

I got a call from this number and they were trying to get my credit card information with the excuse that they were going to lower my interest rate. Being that I did NOT give them any of my personal information they hang up on me. I tried calling back and sounds busy.

BEWARE::: THEY ARE TRYING TO GET YOUR PERSONAL INFO TO STEAL YOUR IDENTITY.

DO NOT GIVE OUT ANY PERSONAL INFO.
