In order to unlink an account from a Bungie profile, you have to have another account linked to it at the time. Since your blizzard account is linked to the unwanted Bungie profile, you'll need to link another account to that profile to unlink your blizzard account. I would create a (temporary) PSN ID (don't use your main one) and link it to the unwanted profile. After you link the new (temporary) PSN ID, you'll have to sign into the profile using the temporary PSN ID to unlink the battlenet account. You can then select [b]Unlink[/b] next to your blizzard account in the profile settings > [b]Linked Accounts[/b]. After you have unlinked your blizzard account from the unwanted profile, log out. Then sign in to your main Bungie profile and proceed through the normal [url=https://www.bungie.net/en/Help/Article/12130]linking process[/url] to link your blizzard account to that profile.
