For instructions on how to change that information, please contact support.
To update the billing information for a credit card you already have on file, you will need to remove the card and then add it back in as a new credit card.
When you change your payment method or billing address, your information also updates everywhere that you use your Apple ID.
If you change your payment method, make sure that your account information matches the credit card information on file with your financial institution.
This means that when you delete details on one device they are deleted from your account on all devices.
