I want to cancel the free trial of apple music

Manage your Apple Music membership - Apple Support - https://support.apple.com/HT204939 - "Learn how to change from an Individual membership to a Family membership, turn off automatic renewal, or join Apple Music later." - this only turns off the autorenewal process. If you must have the entire subscription canceled before the trial period ends you will have to contact Apple: iTunes Support - Use this form for assistance with account and billing, code redemption, or purchase questions - https://ssl.apple.com/emea/support/itunes/contact.html
