I just received a call from this number regarding the lowering of my interest rates on my credit card. I told them I was on the Do Not Call list and the "gentleman" on the other end repeatedly said an obscenity and hung up.
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!
