Hello Jetsarid,
Welcome to iTunes Store Customer Support. My name is Sujith.
Before I begin addressing your email, I would like to sincerely apologize for the delay in my reply.
I see that you would like to receive a refund on the purchase which was never received. I know you must not be paying for a content which wasn't received by your. I will be happy to help you.
Jetsarid, I reviewed your account and happy to inform you that the reported purchase has already been refunded by one of our efficient advisor on 04/19/2015. In just 7-10 business days from the date of the refund processed, the amount of 49.99 USD will be added to the PayPal account which was used to make this purchase.
In case if you have any queries related or new, please reply to this same email so that you don't face any delay in receiving a immediate resolution to the query placed.
Always remember that Apple (and myself) are continuously striving for the best experience possible in making sure our wonderful customers have been taken care of to their satisfaction.
Thank you being a valued iTunes Store Customer.
Have a nice day, Jetsarid!
Sincerely,
Sujith
