HELP WITH ACCOUNT

Hi,

No one will be able to help for this here, your friend must connect to the Enforcement site and raise a case review if he is eligible.

And by the way as he is responsible for his account, it doesn't matter if someone else was able to use it, the suspension will probably not be lifted.

An account suspension would not suspend any other accounts on the console, but a console ban would. Console bans would not be listed on the enforcement site and there is no way to contact the enforcement team regarding them. You can try contacting support
to see if they can check for a ban and to find out how long it is. 1-800-4my-xbox if you're in the US/Canada or http://support.xbox.com/contact-us

You can also find a list of support phone numbers here

There's some steps here
support.xbox.com/.../forgot-microsoft-account-solution you can try to find your email address

or you can contact support here
http://support.xbox.com/en-GB/contact-us

When that happens with the payment options page, it usually means there's an issue that you need to contact support with.

You need to speak with the billing department.
