*The code shown in the image above is just an example and cannot be used in the linking process.
The account linking process can only be performed once between Xbox and PlayStation. Additionally, Support does not have the ability to change the Microsoft account associated with your PlayStation™Network account once linked. While there is in an option in-game to unlink accounts, you can only ever re-link to the original account.
As such, please be absolutely sure you are linking the correct accounts!
Detailed steps for the process can be found in the PlayStation and Xbox account linking article.
