Hi,
Thank you for writing to Microsoft Community Forums.
I understand that you are charged for Minecraft Realms even after cancelling it. I’ll certainly assist you with the issue.
You can manage your subscription within Services & subscriptions while signed in to your account. From there, you can cancel your recurring subscription, which will take effect on your renewal date. For more information, refer the section How to cancel your subscription to Minecraft realms from the article Minecraft Realms and Realms Plus.
For additional information, see How to cancel your Microsoft subscription.
However, for any subscription or refund related queries, we do have a dedicated team, let me point you in the right direction. I would suggest you to get in touch with the Microsoft Store Support team and they will help you with the appropriate details.
Regards,
