Games being Deleted

I have Bought to new games Buisness & Hobbies. I did not get my bonus stuff and after playing and saving and making everything for a week. The app closed out of no where and everything I did and saved is gone. Same happened to when I just bought Love struck. I played for hours and saved everything as I went along. And the app closed in the middle of my game and everything I have saved for a week is gone. So 2 new games and both gone. If you knew how many hours I put into these games. I feel defeated. You guys need to fix this. I am not buying anymore games.
