When you click on it the app say FREE. But then I was charge 2.99 for this app & I wanna know how I get my money back..???

I had this game for 3 days. The App Store said the app is free and three days later they charged me $3.14 without my permission! Do not get this app.

This app is exactly what I needed its based off the same book I have and I can take the test so I no what to expect!

Good for test
