Apple TV+ Cancellation is IMPOSSIBLE

Shame on Apple ....

I'm an older user and currently only have a Windows Desktop Computer and an Android (NO Apple devices).

I subscribed to Apple TV+ and entered all my payment data thru/via my Desktop Windows PC on the Apple site. Now I'd like to CANCEL my Apple TV+ subscription and Apple created only a MAZE of confusing options to do so

Nowhere can I find a simple tab to CANCEL my Subscription???????

Should this cancellation procedure STRICKLY be done on/thru/via my roku? Is it only successful by doing it on/thru/via my roku? No I do not have an active/current iTunes account. Trying that would be another NIGHTMARE ... (discussion for another time)

Can someone please help?

Thank You!
