Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
[Edited to bring following into marked answer]
I am a fellow user, not Microsoft.
What you are paying for is the ability to use the various full-power Microsoft Office 365 applications and One Drive. This is by subscription. You likely signed up for it when you activated a free trial of Office 365.
You can use free online versions of some apps without a subscription.

Thank you for your reply Charles - much appreciated. I did follow your links and have visited my subscriptions and there is no subscription posted for Office 365 and yet it states the next billing address. I also used the 'robot' question service and it appeared to be going well when I acknowledged that I would like to turn off the recurring billing and yet even 'she' encountered a problem. so I am a a bit stumped here????

With the agent, ask to talk to a real person.
Repeatedly.
Eventually you will get a live chat.
