Paying twice?

Re: I have Apple One which includes Apple Music. I also have apple car play. Am I paying twice?

We are all Apple users, like yourself, in the community, so no-one here would have access to your accounts or details. We'd like to help, however:

If you want a list of the apps, subscriptions, music, and other content that you bought recently,

find your purchase history online:

View your purchase history for the App Store, iTunes Store, and other Apple media services - Apple Support

or

See Apple support's article below on how to see what you are charged for:

If you see 'apple.com/bill' on your billing statement - Apple Support

If needed:

Billing and Subscriptions Support have a "Get Support" link at the bottom of their webpage (link below)::
