How to find who bills your streaming subscription
Use the receipt and subscription list to find the correct place to cancel or renew a streaming plan.

Start with the subscription receipt. Look for the seller, purchase account and plan name. The app on your television can play a service that you paid for through Apple, Amazon, a television provider or the service directly.
Trace the current charge
Find the most recent receipt or bank entry. Compare its date and amount with the subscription list on the purchase account. Apple directs App Store subscribers to their Apple Account subscription settings. If the subscription appears as a channel in Prime Video, check the Amazon account where you added it.
Save the cancellation confirmation
Cancel through the company that bills you and save the effective date. Uninstalling an app from the television does not close an account or end a recurring payment. If you still cannot find the charge, check your other email addresses and ask the merchant named on the receipt about the exact transaction.
