Received recorded call about lowering credit card interest rate.  Told to press one to speak with a representative.  Pressed one and was told I was speaking with Crystal from "Consumer Services".  When I asked her if she was aware that she and her company were in violation of the law for calling a number on the national "Do Not Call List", she responded, "Did you know that Do Not Call List doesn't work?"  I guess she's right.  That list doesn't work because I've been on it since it's inception and I still get these calls.
