The game backup feature with Facebook doesn't actually back anything up, and when you message the company to help you recover abd account they need all your card names, their levels, what levels you've reached in the story, a list of dates you've played, and all sorts of other information that the average person doesn't regularly keep track of. If you play, play with caution and don't let them cheat you out of your money and account when you have a phone break and switch devices.
