Hi,
Your Minecraft Realms subscription was purchased through the Microsoft Store app, not the web portal. That’s why your Microsoft account online shows no active subscriptions.
To stop the charges:
Open the Microsoft Store app on the same device used for purchase.
Sign in with the same Microsoft account.
Go to Profile → Settings → Manage subscriptions.
Cancel Minecraft Realms Plus there.
If you can’t find it:
Check account.microsoft.com/services with the same account.
If still missing, contact Microsoft Billing Support and request a refund for recent charges: Microsoft refund page.
Cancelling through the Minecraft site doesn’t stop billing if the subscription was initiated via Microsoft Store. You must cancel it from the same platform where it was purchased. Happy to help!
