Hi makhai179,
Thank you for posting in the Apple Support Communities. We saw you had a question about a subscription or an app purchase, and we'd like to see if we can help.
Can you clarify a bit about the message you're seeing?
Did you purchase it through the App Store on your iPad, or was it purchased through the developer? If you did buy it through the App Store, the links below cover the process for canceling subscriptions and requesting refunds:
How to cancel a subscription from Apple
Request a refund for apps or content that you bought from Apple
On the other hand, if it's a subscription billed elsewhere like through the developer, this should help: If the subscription that you want to cancel is not listed
Kind regards.
