I just received an autobot call from this number saying I can lower my interest rate. Most likely it is a fraudulent scam because they want to get your credit card information before proceeding.
The best thing to do is hang up and report the incident to your local authorities.
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!
