reward redemption BS, press 1 for $100 gift card, ("for visiting one of our affiliate's websites")
Press 2 to be added to our do not call list. (We'll see if that stops them).
It probably won't stop them. In fact, it probably told them yours is a valid phone number. These scammers use robo dialers to call hundreds of numbers. When someone answers or calls back and certainly when someone presses a number, it tells them they have "a live one."
Don't answer when they call again, and look into a call blocker. You'll be glad you did.
What good are the do-not-call reporting procedures if nothing is done????? It occurred to me that perhaps some websites for reporting these calls is a way to offer reporters a device (which costs money) to stop these calls???
