Do you bill Serius XM?

This is a user to user forum. We don't bill anything here.

Apple may be billing you for SiriusXM Depending on how you started the subscription.

If you initiated the subscription on an App on an Apple device, Apple will bill you for it. The charge would appear as "apple.com.bill" on your payment method, rather than as SiriusXM though.

You can look for your active subscriptions on your Apple ID by following the steps in the link below.

If you started the subscription on a non-Apple device or directly through the SiriusXM website (it would appear SiriusXM on your payment method in that case), then you need to contact SiriusXM directly.

For any questions regarding Sirius XM, you would have to contact Sirius.
