How do I solve this problem with an IOS app?

I purchased a Music app from iTunes from my iPhone, it was working fine a while, and then didn't have any sound. I erased it from my phone, and tried to reinstall it. But when I went back to the App Store, I didn't see it listed anymore. I did a little research, and found out it was only supposed to be availalable in For purchase in Grenada. I paid for it, But I can't seem to get it back. Even Apple can't seem to help me. What can I do?

Why r my parants stupid?

My mum keps askin me 2 do things around the house lik cookin and ironin and washing dishes as well as cleaning the whole bathroom and walking the dogs and… I feel lik her slaive bcause she won't even let me hav money for it. I wanted an iphone 6 and she won't buy me one so I've asked for pocket money and she sed no. I'm not doing chores if she doesn't buy me the things I asked for. She chose to have me so I should hav a right to get things I want. When I told my dad this he went off in a huff ann sed he doesn't even want to speak to me coz of my "bratty attitude"excuse me I'm not a brat. I do everythun for them as they sit on their asses all day. Why r my parents so frraking mean. Seriously feel lik cinderella. Help me. How can I get them to stop bein stupud?
