Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Bob,
Thank you for choosing Microsoft Office Community and thanks for providing us an opportunity to assist you.
I understand that you had tried installing a trial copy which never happened. However now you have received an e-mail that it is due to renewal.
If you haven’t purchased the product, then it might be because you tried installing a trial copy of Office 265 subscription. Now, since the trial copy is expired, you have received a prompt to continue with the subscription by renewing every month or on yearly basis.
You may 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 -> Subscription management -> Cancel Office 365 Home Premium Subscription.
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.
I hope this information helps in cancelling the Office 365 Home Premium Subscription.
If you have any additional questions related to Office products you may always post in Microsoft Community.
Thank You
