I can't unlink my Facebook account from this Xbox Live account!

in short old xbox live account lost, still want same Facebook on new account, can't access old xbox account to unlink, and Facebook doesn't show my Facebook as connected but when I try connecting Facebook to new account it says it's logged in to the old
account.

I need help with something a little different. I made an Xbox Live account, and i had linked my facebook to it prior to finding out there was something wrong with it and i couldnt get into it. I closed the account, but didn't unlink Facebook first. Now Facebook
is stuck linked to the old account, with no way to log in to it to unlink it. The new profile has no issues, but i can't link my Facebook to it cause its still linked to the closed account. Can anyone help me with that?

Try to escalate your issue to a supports and pass it to the system engineers provide they can actually do that and look to your unique issue.

I try to unlink the game Modern combat 5 from the xbox account because makes conflict with my facebook account in the game. I make right click on the games list but the option of unlink the game not appear. And the game have not the option for unlink the
xbox account

Whe I open the game take the xbox account information and show an account without progress and new that should play from the beginning, so I must enter the facebook account to recover my game account and all the progress I should have, but if I close the
game the account of xbox again changes the account of the game. I need to unlink this game from xbox before I lose progress and only use the facebook link

Hi there,

You will need to get in contact with Facebook support if you can't locate your account settings to unlink apps with your Facebook account. They should be able to help you with unlinking your account from apps.
