How can I cancel the Apple Music Family Membership subscription if the monthly payment was just charged?

Then try iTunes Support directly: iTunes Store - Contact Us - Official Apple Support

You need to cancel the subscription by following the steps here: Manage your Apple Music subscription - Apple Support

Then request a refund for it to iTunes Billing : Request a refund for an App Store or iTunes Store purchase - Apple Support

Hi there, I’m sorry to hear that you wish to cancel your Apple Music Family Subscription. In order to cancel your subscription, all you would need to do is go to Settings>{Your Name}>iTunes & App Store>Subscriptions, select the subscription for Apple Music Family and simply un-check it. Keep in mind you will be able to access the music until the end of the cycle. If you wish to request a refund for non-usage, you would want to visit http://www.reportaproblem.apple.com and sign in with your Apple ID and password. From there you would just locate the charge and select your reason for wanting to end the subscription. Please be aware that having the ability to cancel immediately and receive a refund will be generated by the website.

Also, please review the following article to understand how cancelling your Apple Music subscription will impact the way your playlist looks and how to readjust your device back to before you enabled Apple Music. Check it out here:

I hope this information helps!

Hello there,

Thanks for your response. As it turns out there are no additional options to request a refund apart from that site. If you are interested in requesting a refund on demand for non-usage and are unable to do it through that site you would need to do it through Apple iTunes Store and Billing Support agents directly. You can arrange for them to contact you by visiting http://www.apple.com/support

Also, if you have any other kind of feedback concerning this process you can visit http://www.apple.com/feedback to provide it specifically about your experience.

I hope this helps!

Good luck!
