I want to cancel

Neither we (other Apple users in this community forum) nor Apple can do that for you. But the link below describes how to do it yourself. I've copied the pertinent part below.

If you want to cancel a subscription from Apple - Apple Support

1. Open the Settings app.
2. Tap your name.
3. Tap Subscriptions.
4. 
5. Tap the subscription.
6. Tap Cancel Subscription. You might need to scroll down to find the Cancel Subscription button. If there is no Cancel button or you see an expiration message in red text, the subscription is already canceled.

If you can't find the subscription that you want to cancel
