Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello
Are they both paid for a whole year, or one of them is paid monthly?
You might want to cancel the one paid monthly. You can go to https://account.live.com > Services & Subscriptions, find the subscription and cancel it there.
As for refund, this is a public forum, so for your privacy and security, we can’t help with billing issues here. Also, no one in this forum has access to your account or payment information.
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.
