If you have subscribed via Amazon Fire TV, then you will need to unsubscribe this way too.
To unsubscribe you will need to go to www.amazon.com/appstoresubscriptions and use your Amazon username and password to sign in.
1. Next to the subscription, select Actions and then a management option.
2. Edit payment information.
3. View billing history.
4. Cancel your subscription.
You can also unsubscribe by turning off the â€œauto-renewalâ€� in your Amazon Fire TV account (image below). This is the same as cancelling.
Unfortunately, due to security reasons, we are not able to unsubscribe on your behalf. However, if you are experiencing difficulties then please contact Amazon Fire TV.
