They over charge your account.
Ok I would not recommend spending any money on this game. I spent $300 just last night yes a little high but the deals were there and I had some spare money. Woke up this morning and they charged me $579. There support tells you to contact the iTunes App Store. So I can see not getting anything back now. Seems like a scam.
