Hi there, To unlink a Playstation account from your Bungie account, you'll need to be able to get access to the account and authenticate it. Bungie will not unlink or authenticate accounts for you. You'll need to get in touch with Playstation Support to help them regain control of your account. I would also suggest looking at the [url=https://www.bungie.net/en/Help/Article/12718]Account Security Guide[/url] and follow it to prevent further actions from taking place.
