Here are some instructions from Google to help you with canceling.
You can also follow these steps:
- Open the Google Play app on your device
- Tap the profile icon at the top right of the screen
- Tap Payments & Subscriptions > Subscriptions
- Select Elevate
- Tap Cancel subscription
Important note: If you don’t see a cancelation option, but instead "Canceled" in red, as shown in the image below, then your subscription should already be canceled.
Additionally, if you do not see a subscription at all, you may be on a free account, which is not linked to any paid trial or subscription and can be used indefinitely. To verify this, go to Profile > Settings > Account Status.
