I want my money back!

I bought this & it was working fine, but then it showed an update, it would NEVER UPDATE! So I rebooted the iPhone, nothing, tried turning wifi connection off & on, still not working. Then deleted the app & was going to reinstall app but it will not add it when you touch the iCloud icon. If this no longer available I should get a refund or the newest pro version. If this is discontinued why is it still in App Store?
