The text message shows that it was taken.

1) If you encounter fraudulent text messages, it won't cost you money if you don't mention it now. The other party mistakenly thought that the bank card information was leaked in the tone of bank customer service, so you called them for help and then fell into their fraud trap. There are three characteristics to judge this situation: a. The sending number is an ordinary number, not a bank customer service number. B. The customer service number mentioned in the SMS is not a bank customer service number, but another fixed number or mobile phone number. C, short messages are incoherent, with strange symbols or typos.

2) You did suffer a loss of money. Maybe when you use the self-service deposit machine to withdraw money or spend money by credit card, others steal information, and at the same time, because you didn't pay attention to protecting your password during use, criminals copied the bank card and directly used the copied card to withdraw money.

3) There is a system error when the bank processes the short message, and other people's withdrawal information is sent to your mobile phone number. This situation is less likely.

In any case, you can call the customer service hotline on the back of the bank card or go to the bank counter to verify the authenticity of the account change. If you encounter fraud, you should call the police in time.
