Yarr ! I finally got my reply. Does this apply to you ?
Dear Customer,
Regarding your request for account support. Please find your answer below.
If you accidentally registered your FINAL FANTASY XIV: A REALM REBORN Registration Code to the incorrect Service Account or Square Enix ID, we will be able to offer a one-time assistance after you verify your account. For issues in which the code was registered to the wrong Service account but on the same Square Enix ID please visit this page:
https://support.na.square-enix.com/cont ... a=1&daxx=2 For issues in which the code was registered to a second unintended Square Enix ID please visit this page:
https://support.na.square-enix.com/cont ... a=1&daxx=1 * We are only able to provide assistance if the account information for the Square Enix account on which the code was mistakenly registered and the intended Square Enix account match. * This recovery can only be performed once per account.
Thank you for contacting the SQUARE ENIX Support Center.
