Hello I would like to help you with this.

Your best bet to resolve this is to contact XBOX technical support.

They can fix this for you and can get your new Xbox assigned to your account.

I had a similar issue with mine.

You can contact them here

Please remember to rate my answer "Great Service" This is the only way I will get compensated for my time helping you.

IF you feel the need to click either "Helped a little" or "I expected more", please stop and reply to me via the CONTINUE CONVERSATION button with the issue you have. I will be happy to continue further and do everything I can to provide you with the service you seek.

If you are having trouble with the site or rating system please let me know as this is a new feature and some Customers have had some trouble with it.

Thank you,

Carl,
