Regarding RFE Clear

In My case me and my teammate same got RFE. We have submitted all the documents incuding MSA not SOW. His case got approved before Thanks Giving Day. But I was still waiting to get case approved. Finally I went for Premium Processing and with in 2 days my case got denied.

I dont know why my case got denied and my teammate case got approved. And we have submitted same documents. Please help what can be a reason?
