IPhone 5, incorrect billing info, but stuck at installing? What do I do?

I tried to buy a game called Modern Combat 4. I was in the process of entering my billing info when I somehow accidentaly hit the magic spot on my touch screen to move forward. The billing info is obviously incorrect regarding the billing address, and now I can't "purchase" the game. I can only try to "install" it. It gets stuck "waiting" on the main screen. At the app store, I can install it from the cloud.

Nothing happens because I don't own the game. I want to purchase it, but it didn't reset my info. When I delete it and go back to the app store, it shows a cloud I can try to download it from, to no avail.

Turn the phone off for a little while and turn It on again normally this should help.
