Lost free 30 days for accidentally registered to the wrong service account?

[dropshot]

To those still in unable to access EU Chat Support, here is what I did:
1. I went here,
2. Clicked "This did not answer my questions"
3. Filled a ticket with category: Account/billing, subcategory: Registration Information
4. In the contact details, submit either "Early Access Code Incorrect Registration" or "Incorrect Registration".
5. Scroll down and click "Chat Support".

This seemed to work. I got support right away. They said the will escalate this immediately. Keep in mind that you need to keep the following information of the account at hand

Square Enix ID
E-mail address
Date of birth
The code that you registered to the wrong account.
