Where in the wild wild world of sports is the link to change your billing account details in ESO?
"Edit Account Info" ...You can only change you Name ID, address or account email
"Manage Membership" has a place where you can put your card details in, but it seriously reads like you will be billed immediately once you hit "pay". I don't want to do this as I have a few weeks left on my existing account before it becomes due again.
Is this the place I go to? Will I only be billed again once my current gmae time expires?
