Xbox linked account

Hello Bungie,

I need some help with my linked Xbox account. I need to unlink it. Somehow, there was a mix-up in my email, and it linked to a brand-new account that it created when I entered the email provided, which has no play time on any game on my account. As you can see, it's a brand new account. I need to enter the correct email address to link my actual email, which has hours clocked hours of game hours over the past decade. Also, I never got help on my last forum regarding the Discord drops for the liquid cheeseburger. Your help would be greatly appreciated.
