How can I remove a recurring app usage fee after cancellation?

I’m currently charged an app usage fee for Auto-DS for my store but i didn’t use that app and i cancelled there subscription so how can i remove that recurring bill

If you uninstall the app, the charge is cancelled.

for refunds, you should contact the app developer directly.
