I forgot how to get my money back!!!!!!

Look Im 11 years old, I let my little cousin play on this game because I never play on it. So, I game him it and he played for a bit. He accidentally bought it for 5 dollars !!!!!!! Can someone help me get my money back. Also you should really let us,children, unlock them like the pirate not pay money

Thank You,
