If you lost/broke your phone, you still can cancel your app subscription using iTunes. This gave me a headache and finally, I found the solution.
1 – Download load iTunes and log in using your Apple ID.
2 – Click on the Account menu and choose View my account menu item. You will see all your account information. Scroll down and click on subscriptions (as seen in the picture below).
3 – Click confirm to cancel your subscription.
