My account is hacked by someone and they took my email ... I tried making an account with the same account and said I've been banned from account creation
You can not create a new account with the same email address. Microsoft does not allow the reuse of an Account ID even if the original account has been closed or the alias has been removed.
Even using a new Account ID, you may still have problems with Account Creation. There is an ongoing service issue.
