The world is not fully syced or has been corrupted

Hello 
 
I looked over what was sent to me and I didn't find any solution, regarding my world on mimecraft, I changed my xbox from one one s to a much better one, before I always left the world  waiting to be saved I never came out without saving, now to receive the message that it can not be synchronized, how ?, if I stayed to save and I made synchronizations every time, I want a little attention, on the phone,  connect someone specialist to xbox to solve the problem, I do not understand when you say you can not, you really can but you do not want is a difference, please send me a good answer, call me by phone and tell me the steps how  connect a consultant to the Xbox or an update, but I received one now and do the same, even before with this problem.

Pictures in the last complaint.

The problem is not resolved to be marked as resolved
