How can I cancel my iTunes subscription and get a refund?
Subscriptions bought via iTunes (for iPhone, iPad and Apple TV) need to be managed via iTunes. While we are informed about your subscription status by Apple, we do not manage and control your subscription and payments.
Emails about your subscription will be entitled Your invoice from Apple. You can find a link at the bottom of this email which directs you to the refund process.
