I've had my old Bungie.net account since around 2008. The username/ID is "The Assassin575." Back when you could register for a Bungie account with nothing but an email address, I unlinked my Xbox (Microsoft) account from my Bungie.net profile. Then, however, site updates were implemented that require you to sign in with an existing Microsoft, Playstation, Google, or Facebook account. Since my account was not linked to anything before the site update, I now have no way of signing in to it. Is there any way to get my lost account linked to my Microsoft account so I can continue using it?
