Unplug credit card from lost account?

Is your whole Xbox account locked right now? If so, you need to talk to Support and have it unlocked and then you can go into the Subscriptions and change the payment methods there or remove the credit card on file, or cancel subscriptions.

I called polish support, and the lady said she can't do this when account is blocked.

Hi there,

for an issue like that it's usually best to contact Xbox Support via Phone (or Chat) at
http://support.xbox.com/contact-us

for advise on what steps are best or if they can assist.

Let it know when there are any results

Hello Neespa,

Thanks for reaching out, I can provide you some details to help you out. If you are unable to locate the email address or gain access to the account in order to recent the password as well as Support unable to assist due to the lock on the account. I'd
recommend reaching to your Credit Card company to see what recommendations they have if you're unable to gain access and are no longer looking to pay for the membership.

Hope this helps! Happy Gaming!
