I need to close an old account which has recurring billing. I don’t have access to the Xbox...

Thanks for clearing that up. If you still have the username then I would highly recommend you contact the support team so that they can check on their end if it is still active. You can contact them using this link, https://support.xbox.com/en-US/.

Thanks for replying

The issue is the email address does not exist anymore - it was with Virgin UK & had been closed.

I have the Xbox username

Hi, Fiona. My name is Ron, I'm an independent advisor. I will be more than happy to help you.

Please try using this link first to see if you can recover the correct email using an alternate email or phone number that was linked to the account, https://account.live.com/username/recover.

If that doesn't work, please try the steps from this link to recover the email address that is linked with the subscription, https://support.xbox.com/en-US/help/account-pro....

this page will walk you through the process of
Resetting or Recovering your Microsoft account.

If this doesn't help, or this is not the issue, please let us know, also it might be worth contacting customer support.

If you don't have access to the account there's a few options you can take, the first of which would be to try and get into the account through the password reset/account recovery tool. Do not go through that method if you do not own the account. Here's
the pages for that:

If you don't own the account, and need to cancel the subscription, you'll have to take a more direct approach. You may have to call your bank should you not be able to get into the account online or through an Xbox to view your subscriptions services. By
calling your bank, and telling them that this service shouldn't be charged because you didn't authorize it to be (or something in that vein) everything should be handled on that end. Worst case scenario, you'll have to simply get a new bank card so the subscription
eventually cancels itself on a card that no longer exists.

I'm recommending you contact Microsoft Support for billing first, then Xbox Support (but I think its one in the same), see about getting it manually canceled should you not have access to the account. While someone renewing that subscription through your
bank/card is technically fraud/fraudulent activity (if its occurring without your approval,) so is trying to get into an account that's not yours.

Try to get into the account, if it is yours. If you know the person who's been charging that subscription, get them to pull up the subscriptions page online or on the console so that you may remove you billing details/cancel the subscription. If neither
of those are true, consider contacting support by phone first... and then calling your bank if need be.
