How do I change or update the credit card on my account?
To change your payment method, go to your Account Settings, scroll down to the Payment Options and modify the settings there. If you are trying to change the billing address, you will need to remove the card with the old address and add the card again with the correct address. At this time you cannot edit the billing address on an existing payment method.
Please note, any changes to your billing must be done at least 24 hours before the account renews itself.
