Criminals often commit fraud by posing as bank staff via phone calls or text messages, and defraud customers' funds on the pretense that the bank sends gifts to cardholders but must pay a certain amount. If customers receive such calls or text messages, please call the Bank of Shanghai customer service hotline in time to verify the situation. Do not trust unknown phone calls at any time, nor do you believe that you can increase your credit limit, give gifts, or get points by paying a certain fee. And remember to keep personal information properly.
