How do I cancel auto payment to USO.

Welcome to Apple Support Communities reyaviles3,

We want to make sure we're on the same page. Is the auto payment for a subscription through Apple?

If so, you can follow the step here: How to cancel a subscription from Apple to cancel it.

If it isn't though Apple, you'll want to reach out to the organization itself or your financial institution for further assistance.

Have a good one!
