Greetings,

I am sorry for the inconvience your having. Please let me try to help you a little bit.

As solution, please, first check http://billing.microsoft.com to see if there are any errors or wrong information. If there are no problems there please try to remove your payment option and re-adding it to see if this helps. If that doesn't work can you please try and changing payment methods (ex: PayPal) to see if it works then and if it doesn't please call 1800-4MY-XBOX and ask for Billing and they should be able to sort it out for you.

To re-add a payment method:

1. Navigate to the Settings Hub and select Account.

2. Under the Your Billing Options panel select Manage Payment Options.

3. Select which type of payment method you wish to add: Add PayPal or Add Credit Card.

4. Fill out the required info and select Next.

Also, please take some time to read this article http://forums.xbox.com/xbox_forums/xbox_support/f/27/t/153161.aspx

Please let us know your progress.

Sorry your having issues with your xbox.  I found this ( taken from a friend, thanks Snp)

 First thing is do you think you can check http://billing.microsoft.com to see if there are any errors there. If there are no problems there can you try removing your payment option and re-adding it to see if this helps at all. If that dosen't work can you please try and changing payment methods to see if it works then and if it dosen't please call 1800-4MY-XBOX and ask for Billing and they should be able to sort it out for you. I hope this helps! 

Let me know good or bad.

Late again, sorry to above.

EDIT: You should also try to create a topic here forums.xbox.com/.../27.aspx this is the right place to ask this kind of questions.
