I don't know how these scumbags get all of these numbers, computer generated, I guess, but I have reported to the FCC, what a joke. It is a direct abuse of our rights.
Well, I have received several of these scam credit card rate lowering calls. You can't ask them to stop calling because they immediately hangup on you. Leaving a vm with them is impossible because their boxes are full. So what I do is wait until a person comes on the line and engages me in conversation about their crap and I blow a boat air horn at them.
