This is a scam. They call saying that there is a problem with the interest rate on my credit card but don't indentify the card. They want the account numbers, address and SSAN so they can get the rate lower back to where it is suppose to be. They also have a little trick to try to fool the caller ID. They add two digits to the front of thier number as though it was an international call and the caller ID looses the last two digits of their real number. It looks like this: 442-074-0774. Because I do a lot of international calling, my called ID is set up for it and it looks like this: 44-207-407-0774
