Can I get a Refund for apple music

All purchases are considered final but you could try the 'report a problem' page to contact iTunes Support and see if they will refund or credit you : http://reportaproblem.apple.com

Or you can try contacting iTunes Support via : https://support.apple.com/contact or https://www.apple.com/emea/support/itunes/contact.html

And if you no longer want Apple Music, and if you haven't already done so, you should cancel its subscription : View, change, or cancel your subscriptions - Apple Support
