Absolutely! This number is not from CCB! Never call back, in case the card information is cheated and stolen! Nowadays, many fake text messages are sent by pseudo base stations, and they are defrauded in the name of quota adjustment, frozen cards, expired online banking, and discount points. CCB will not ask you to call back, nor will it ask you to register your card and personal information. When you receive an unknown text message or phone call, first check the authenticity with CCB customer service hotline or branch staff, and don't rush to operate!
