This number says it belongs to Card Member Services. They are Phishing For Credit card numbers! I ask them which card they were calling about and they keep on with the questions for me trying to get me to tell them which of my cards I want to lower the interest and payment on. I tell them I didn't know I even had a Credit Card and they insist I do as "Everyone has a Credit Card". I just hang up or don't bother to answer...they call about once a week.
