How to cancel membership

Did you cancel the subscription more than 24 hours agead of when it was due? If not then you are liable for the first payment.

To cancel the subscription see Manage your Apple Music subscription - Apple Support

Strictly speaking all purchases are final - after all, you can't very well return them: please see this page for information on requesting a refund:

However Apple have been known to be sympathetic in cases of error, so it's possible that they may allow you a refund as a one-off concession: however please be aware that they are under no obligation to do so.

Go to https://www.apple.com/emea/support/itunes/contact.html or https://reportaproblem.apple.com/?s=6 as suggested in the page linked to above.
