Hi Natklao,
Thank you for contacting iTunes Store Support. My name is Elvie and I will be your dedicated Advisor.
I understand that your son had made an accidental purchase for "Jurassic Park Hard Cash Package 1”. I know how important it is for you to have this addressed right away. Rest assured that I will provide the best resolution.
I’ve reviewed your case and am issuing you a full refund for the purchases.
Within ten business days, 1.99 USD, an tax maybe included and it should be posted to the payment method used to make the purchase.
There are several ways you can prevent unintentional or unauthorized purchases on your iPhone, iPad, or iPod touch. You can disable in-app purchases, disable purchasing completely, or require a password for every purchase.
To learn about placing restrictions on in-app purchases, please see these pages:
