I received a text message from the legal department about someone else's credit card.

It means that this Kaka number has been used by others before, and that person abandoned this card without cancellation number.

Because the mobile phone number we are using has been used by other users for a long time, which may be bound when we apply for a credit card. This situation will not cause any risk to you, nor will it affect your personal credit information. If you don't want to accept such short messages, you can set up a screen on your mobile phone to block such credit card information. People who don't know how to use credit cards will always have text messages sent to your mobile phone. Obviously, this is caused by a third-party dunning or bank dunning platform. The owner himself can call the customer service of the bank who sent the text message to explain that he is not the person mentioned in the text message and ask the other party not to continue to send text messages or telephone harassment, otherwise it will be handled as a complaint.
