Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello,
Because this is a perpetual license, most of the AI answers don't apply. You need to get in touch with billing directly in your case. Typically this is not refundable, but if you explain to support, they might make an exception.
To get help, open the "Get Help" app on your computer (just search for it in the Start menu). or go to https://support.microsoft.com/contactus, Type "Billing" and press Enter. On the next screen, click "Contact support" at the bottom of the page, then choose "Microsoft 365" > "Manage my subscription". You’ll then see the option to chat with a Microsoft support agent who has access to your account to help review the issue.
