I uninstalled (deleted) the application, but the charges for the premium pass haven’t stopped.

Uninstalling the app will not cancel your premium pass subscription.
Please note that until you follow the steps to cancel your premium pass, the payments for it will automatically continue.
Also, even if you have canceled your subscription, your premium pass will remain active until the expiration date.
For more information about how to cancel your subscription, please see I no longer wish to subscribe to the premium pass. How do I cancel automatic renewal of my subscription?
