Scammers using robo-dialing, and spoofed caller ID info. You can report tham all you want - this isn't the number they are really calling from. They don't care about the DMC list. They aren't selling anything or offering any services. They will tell you any kind of story they think will get you to give them a credit card number, so they can rip your card off. Ignore them, but complain to your US Senator and/or Representative. There is no reason the phone companies can not be forced to stop this insanity.
