Hello, it has been sent and cannot be changed. If you need to change it, you need to apply for a new card, which takes 2 working days. I suggest you wait patiently. Registered mail will be quick. It usually takes a week or two to receive it.
If in doubt, please add enterprise QQ customer service 4008205555 or WeChat to WeChat official account "China Merchants Bank Credit Card Center" for detailed consultation.
