3.21 is the time for meter collection, not the time for approval. The specific time for approval cannot be found online. It is possible that your card has just been approved today, but the customer service does not have the latest updated information yet, so it tells you that it is still under review. It is recommended that you call the CCB credit card customer service hotline (call tomorrow) and select the application progress query in the voice service. If there is a broadcast date of approval, it means that it has indeed been passed. Within 3 working days after this date The card will be printed and mailed. You will be notified by text message after it is sent. Generally, you can receive it within 10 days.
