Can't pay past due bill for Xbox game Pass Ultimate

here is a link to all the info on past due balances and how to pay them.

https://support.xbox.com/en-US/billing/xbox-subscriptions/pay-past-due-balance-on-xbox-subscription

depending on when it was set to renew, you may be able to pay the balance and then request a refund, or, if the past due subscription is for Live Gold and you wanted to take advantage of the deals on Game Pass,
Ultimate you can simply pay the outstanding balance and then upgrade to Game Pass Ultimate and any time left on your Live Gold will also be converted to Game Pass Ultimate

if you used Gold or Game Pass or Game Pass Ultimate after the expiry date and recurring billing was turned on but there wasn't enough in your account to pay for it, it would get a Past Due Balance on the account.

this Past Due Balance has to be cleared before any other purchases can be made with that account.

the following link has all the details on how you can pay the balance off

So, apparently, the account becomes locked when non-payment happens....seems you either need to provide another funding source to unlock it (ie a difference credit card etc) or cancel the current sub and then start a new one:

You would need to contact support and speak to billing and they should be able to get the payment sorted out. http://support.xbox.com/contact-us

go to https://account.microsoft.com/services and turn off recurring billing/auto renew on the Game Pass Ultimate subscription before you get a Past Due Balance on your
account.

if you get a Past Due Balance you will need to pay that off before you can get Live Gold or Game Pass.

wait till the Ultimate Game Pass Expires before getting Gold or it will convert to Ultimate Game Pass
