I can't find an app that I purchased (wasn't free) anywhere? There is an app called "Calum Von Moger Fitness" and I bought it and stupidly deleted and then when I tried to find it again I couldn't! Strangely I cannot find it in my app purchase history.

I am not happy because I paid for this app and it just disappeared!
