here's the scoop. I registered on the donotcall website in '05 and i now have 10 numbers that keep calling our home. This particular number is a non-working number of American Express!?!?! whatever that means. I sat and called all these numbers that were calling me to see what or who they were. As soon as i can i'm filing complaints on them all! What good is the donotcall registry if they still call?
