can i get a refund for a subscribe game? £44 has been taken out of my bank for a game ive never played on

Have you checked your iTunes account's purchase history (and family members accounts if you are a family organiser in family sharing) : See your purchase history in the iTunes Store on a Mac or PC - Apple Support ?

If it shows there but you didn't buy it, and if nobody else has access to the account and did it, change the account's password if you haven't already done so (What to do after you change your Apple ID email address or password - Apple Support) and contact iTunes Support : http://reportaproblem.apple.com or https://www.apple.com/emea/support/itunes/contact.html

And if it does show : View, change, or cancel your subscriptions - Apple Support

If it doesn’t show on your account(s) contact the card issuer.

There isn't a number. You can contact them via http://reportaproblem.apple.com/ or http://www.apple.com/support/itunes/ww or https://www.apple.com/emea/support/itunes/contact.html

Purchases are considered final, any refunds are at their discretion and are likely to be a one-off on the account
