Live chat support.

You would find it at http://support.xbox.com/contact-us If you don't see it listed, change the category/topic until you do.

Support no longer uses an email.

contact xbox live chat support, or activision live chat support, they should be able to explain why or sort it.

Hi,

Thank you reaching out!

You can contact support via chat
here.

Hope this helps!

Hello,

Sometimes, depending on the specific issue that you're experiencing Live Chat will not be available. If you're being told to contact customer service via the phone number directly, please do so. You can find your country/region's phone number
here (this is taken from whatever region your LIVE account is registered to).

Hi, to add to the previous comment, certain help topics may give you links to web guides to help solve the issue rather than chat options. If you don't see a specific option at the
support page that reflects the specific nature of your issue, try selecting "My account" and skipping the virtual agent, then select either "Manage account" or "Error messages
and codes" and I think you'll see a chat option and/or an option to request a call from support. Hope that helps!
