I have had this happen. What you can try, is call Apple and request to speak with the iTunes department. This was years ago, but they were able to restore my lost ringtones as a one time exception. I have no idea if they still offer this, but you can certainly ask. I lost a total of three ringtones and all three were restored. Good luck.Every freaking time I move to a new phone I loose my ringtones and alerts purchased through iTunes. Any help.
