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!
Received a call from this number - the caller ID said "Texaco". They obviously didn't know what kind on credit card I had, but were offering to lower my interest rate. The person on the other end spoke such weak English that I could barely understand him. I finally hung up.
