Hi there, Thanks for your report. You must be able to authenticate your account to unlink it. I would suggest reaching out to Playstation Support regarding the banned account. If you are unable to gain access to your Playstation account, then you will not be able to unlink it from your current Bungie.net profile. If you're trying to set up cross-save, then your only option will be to create a new Bungie.net profile and then unlink/relink the accounts you actually want to that new Bungie.net profile. Please note that if you decide to create a new Bungie.net profile, you will lose access to the code-granted bonuses you've redeemed on Bungie.net because they are tied to your account.
