Hello there[url=https://cdn.discordapp.com/attachments/902560216871239752/978300950097842206/giphy.gif],[/url] In order to unlink an account, you must be able to authenticate the accounts. Bungie cannot forcibly de-link them. [b]I would suggest contacting the platform concerning gaining access to the platform account.[/b] If you are unable to gain access to the account, then you will not be able to unlink it from your current Bungie.net profile.
