Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Dihao, I appreciate the reply, but I do not think you fully read my OP.
Steps to cancel your subscription
If you added your own domain name to use with your subscription, you must remove the domain before you cancel your subscription. For more information, see Remove a domain from Office 365.
- In the admin center, go to the Billing > Products & services page.
- Find the subscription that you want to cancel, and under Settings & Actions, select Cancel subscription.
If you read nothing else, please read this bit:THERE IS NO SUBSCRIPTION TO DELETE ON THE PRODUCTS and SERVICES PAGE!
I appreciate that you may not convinced, so here is a screenshot:
