In recent months, the Pacific Credit Card Center of Bank of Communications is in the stage of system upgrade (electronic card processing system), so some applications may be delayed. Because the system is unstable now, the processing of credit card applications is not so stable, it is only a matter of time, and there is nothing else to worry about.
In addition, there is another possibility for you, that is, you have entered the front-end anti-fraud system. This is not about what happened to you. It's just a bank spot check, so the audit is strict and the time will be longer. As long as your work unit is real and the information you fill in when you apply for a card is true and effective, then you don't need to worry and wait for approval.
If the application is not approved, you can apply again. This has nothing to do with it. Many people have applied several times because there are problems in the whole process of bank review, such as calling the company to say that you don't work here, so you will refuse the card, such as these situations, so don't worry.
What that brother said, "If you don't apply once, I will blacklist you for whatever reason, and you will never apply anyway" is pure nonsense, and there is no similarity.
If you don't understand, please ask questions and hope to adopt them.
