Yes i know that but they are don't helping me. i want to change it in my xbox live i want to unlink it and creat new account

I was created shift account and it say i need to conect my shift account with my xbox live account. Can any explain to me how i can do it? Please help.

I managed to set up an account through with the website and that let me do parental confirmation. Now I have a problem that the XBox won't let my son log in to XBox Live with it and he cannot use the email address to create another account and it wouldn't
let me do parental confirmation if he did. The XBox insists he creates the account through the XBox only but won't let me do parental confirmation so even if he created a new email address it wouldn't help.

You should try creating the Xbox live account on Xbox.com, after its created recover the profile on your 360 console. If you already created an xbox account try signing onto it on xbox.com if you can access your account on the website they they might
be having Tech issues on Xbox live right now. I hope this helps!
