??? well theres 2 buttons on that page
one for gametime code
one for credit/debit card
if i was wnting to use a cc i would pick the later and simply add your cc details when prompted to do so.
if i was using a gametime code...far cheaper..i would use the first option then enter the code when prompted to do so
I can only tell for my (very little) experience with the new system, not sure if it is being any different for other players (I say this, because, for example, I saw an image posted by someone of an Account management page that carries on the top right corner a box to select languages and I have no such box on my page so, apparently, there may be differences...).
After I linked the account, selected it and went to billing and selected the 6 months plan (crossing my fingers that I do not get double billed.....), I got sent to another page for the credit card payment.
This page had only 2 buttons, very large buttons, one to select for payment my
existing Credit Card, the one that I have used so far, and the other button for a brand new Cradit Card.
Of course, I pressed the button for my existing existing Credit Card to be billed whenever my current paid for time will expire (which, if I got it right, will be on October 4) but that was it. There was nothing else I could do other than press a button. Nothing that I could see to edit my Credit Card informations or, for example, update the CC expiration time......
