I have a twitch account linked to my bungie account that I no longer have access to or is deleted, I'm not really sure. I don't know the twitch account's email anyway so I'm locked out of it and, like I said, can't unlink so I can link my newer one so I can get the emblems from the official streams when they happen. I'm hopping that maybe Bungie themselves can unlink it for me since it's not a game account.
