Wont download

So I was looking forward to going on the app, and it wont work. It says I downloaded it, but its not anywhere on my iPad and when you go on App Store and it either says open or install, it says open and it wont let me open the app!!!! I am getting very angry at this and it is very frusterating. I am not happy with this app and I would like it fixed, thank you.
