Hi ,
I'm Dyari. Thanks for reaching out.
I am afraid that no one here has access to Microsoft accounts. Before asking for a refund, make sure auto-renewal is turned off so you do not get charged again. Sign in to your Microsoft account > Go to Microsoft Services & Subscriptions > locate your Realms subscription> Manage > Cancel subscription or Turn off recurring billing.
https://account.microsoft.com/services
If your request is denied, you can contact Microsoft Support:
https://support.microsoft.com/en-us
Select the product > Get Home Support > Type billing > Sign in to Contact Support > Select the product and then click Chat with support agent in web browser.If you bought the subscription through a mobile device or console store, Microsoft cannot refund it directly. You must request the refund through the respective support team.
