We keep getting calls two to three times a day from this phone number.  My husband answered by mistake one day and they wanted to go on and on and on with him about reducing credit card interest rates.  To me this is a scam where they want to get your credit card numbers and personal info.  I don't give out anything to anyone over the phone unless I absolutely know who I am conversing with.  To lower interest rates is something we, personally, can do on our own without providing them with ammunition to destroy our identity.  The DO NOT CALL registry isn't doing what it claims it will do in stopping this nonsense.  My husband will pick up on calls like this but I DEFINITELY DO NOT!!!!!  Don 't need the constant harassment.
