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 number to these junkies have suffered severe financial losses. Beware of these lowlifes, and warn others, before they are cheated!
Actually, the "card services" scammers generally use a robodialer, which dials numbers in a sequential order, regardless of whether the numbers are on the do not call registry, are cellular, or is an unpublished number. These creatures are nothing but criminals, and have no intentions of obeying any laws or regulations.
THE DO NOT CALL LIST isn't what's its supposed to be. Have registered with them and have received more if these types of calls than before I registered with them
