So just to update everyone on this situation. I contacted Sony support again
Gloria: I can see that Stormblood Collector's Edition was pre ordered. No worries, in this case, you will be able to download the content, the steps to register are: Open FINAL FANTASY XIV and follow the instructions on the screen. You will see "FINAL FANTASY XIV: Stormblood - Pre-Order PlayStation 4." Select "Next." You will see the service account onto which you can register the pre-order code. Select "Next" to complete the registration process.
Me: do you know when the registration can take place?
Gloria: Yes, I definitely understand your concern. We have reported the issue and our specialists are working on that. It is scheduled on Friday, June 16, 2017 at around 2:00 a.m. (PDT) (There will be maintenance before early access starts. Due to the maintenance, the early access schedule is subject to change)
So it seems we will have to wait until the day of early access to register for SB
