Hello there[url=https://media.giphy.com/media/KOVlHmbBA09XO/giphy.gif],[/url] In order to unlink an account, you must be able to authenticate it, which means you must be able to log into it. Bungie cannot forcibly de-link it. [b]I would suggest contacting the platform concerning recovering the platform account.[/b] If you are unable to gain access to your account, then you will not be able to unlink it from your current Bungie.net profile.
