Hello! Although I don’t know what the circumstances of the call you mentioned were from the Bank of Communications Credit Card Center. But I have the following situations for your reference. 1. If the bank calls you during the credit card application period to verify that the information is not received, the staff will call again. 2. If you already have a card, there are many situations. As long as your credit history is good, the theory doesn't matter. In short, if you are not sure whether you will receive a call next time, it is recommended that you take the initiative to call the bank's manual service to find out the specific situation. The same goes for any other time, bank customer service will answer your questions, good luck.
Finally, one more thing, there are similar questions and answers to your question on Baidu, but you may not have searched for it.
