Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
Thank you for choosing Microsoft Office Community and thanks for providing us an opportunity to assist you. I understand how frustrating this is as you are being charged for the subscription though you have cancelled it.
Did you cancel the subscription or deactivated the Microsoft account?
If you have already cancelled the subscription, and still being charged, refer to the following link, go to Getting Help and click on Contact Customer Support.https://commerce.microsoft.com/PaymentHub/help
Once you are in the window, under Products select Office 365 Home Premium -> Billing and Payments-> Getting a refund.
You need to click on Start chat or Request a call option to talk to representative who will be able to assist you regarding the Office 2013 and other related information.
You may also refer to the following article on Manage Microsoft Office billing options and follow the steps to get a refund for Office 365 subscription:
