The callers are the drug-addicted "card services" scammers, who call us, pretending to be associated with our credit card companies, in an attempt to fool us into giving them our credit card numbers, so they can rip us off. People that have given their card numbers to these junkies have suffered severe financial losses. Beware of these lowlifes, and warn others, before they are cheated!
Sandy they have never stopped. They spoof numbers and this one is obviously being recycled.
Also, remember that the DNC is just a List that is only honored by legitimate and registered with the FTC American based businesses. The ones calling are criminals and like all criminals could care less about the laws.
