Unfortunately we are not able to provide you with a refund directly. To claim a refund contact Apple here.
There is a good reason why we can't do this for you - Apple's privacy policies restrict our access to your payment, as well as the payment details linked to your Apple ID. This means that only Apple is able to process a refund for you.
