Refunding of unauthorized purchases made to Apple iTunes

My account was debited without me authorizing or singing up for any service. I do not have an apple phone, nor do I have an iTunes account or any other person in my family. This morning I checked my bank statement and to my shock to see my account was debited several times (Recurring Card Purchase: Apple.com/bill Itunes.com (Card 0400)) with apple subscriptions. Furthermore, I tried to contact apple via email regarding refunding the unauthorized purchases made - this has proved to be an impossible task. U have to create an account, and after creating an account, u have to have used iTunes to before making any kind of dispute.

Could u please point me in the right direction to have these purchases refunded to my account?
