Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello
Do you have an Android device? If so, on your device, Open the Google Play Store app.Tap your profile icon in the top right corner.Tap Payments & subscriptions, then Subscriptions. See if you can find the subscription matching this.
Also, even if this is for a Microsoft product, but if you signed up via Google Play, all billing support is managed via Google, not Microsoft.
