It is not a subscription that is managed by Apple and you were most likely directed there from a Social Media post or website advertisement for a free astrology reading. The free reading was part of a free trial that turns into a subscription if not cancelled. You did authorized it, but were tricked into believing that you were just getting the free reading.

Since Apple has no part in this subscription, you must deal with Astroline directly for cancelling. They offer the following instructions:

To cancel your web subscription, open the Astroline web app and follow these instructions:

1. Log in to your account using the email and password you’ve created when subscribing to Astroline. 
2. Tap the gear icon at the top right of the main screen to open ‘Settings’.
3. Scroll down to the ‘Manage Subscription’ section and tap it. 
4. Tap the button ‘Cancel Subscription’ at the bottom of the screen.

They also have this web page with information on their limited refund policy along with cancelling your subscription.
