wont let me pay for past due subscription

The
pertinent info.

I'm not sure why, but overdue payments have to be made with a credit/debit card. Probably because you had a card on your account, as subscription cards wont ever go overdue.

What you'll have to do is add a new, valid payment option. Pay your overdue balance. Cancel the subscription renewal. Then use your subscription card. Sorry its a headache but as far as I know, there is no other way.

You would have to try contacting support and see if they can do anything else, but otherwise overdue balances can only be paid with a credit card or Paypal. http://support.xbox.com/contact-us

You'll need to contact support and speak to billing. 1-800-4my-xbox if you're in the US/Canada or http://support.xbox.com/contact-us
