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!
I called back to the number and the person told me that they were visa/mastercard. I know for a fact that they are two seperate companies, but he insisted that they were one company. When I asked to have my phone number removed, he disconnected the call.
