Hello Gladys HU, Welcome to the Microsoft Community. Thank you for supporting Microsoft, I understand that you want to replace your payment card. You can visit account.microsoft.com and go to Payment Options, where you can remove your old card and add a new one.
As community support staff, we don't have access to your account and orders, so if you're having trouble changing your payment method, try contacting online support for further assistance:
- Go to the following Web site: Contact - Microsoft Support.
- Enter the keywords of your question in the search box, for example, "subscription/refund" and select Get Help.
- Select Contact Support (sign in to your personal Microsoft account).
- Under Products and services, select options related to your product, like Microsoft 365 and Office.
- Under Category, select Manage my subscription.
- Go to Confirm.
Please Note: The Chat support team only works at certain times, so if the last window says you are not available, try to open it again the next day. If you prefer phone support, you can leave a phone number. That way, they can call you and help you.Best RegardsEliac.S - MSFT | Microsoft Community Support Specialist
