ONGC — Not received renewal scholarship.

I recieved Ongc Scolarship in my 1st year[protected].
I applied for the renewal of the scholarship in 2nd Year, But I didn't received the scholarship.
Later I got mail from ongc to update required details and document on ongcscholar.org. I have updated all the required information.
Sir, it's been a almost 6 month, I have updated all the required documents but I didn't receive 2nd installment. I applied for 3rd year but didn't received the scholarship.Many of my friends got the scholarship along with me in 1st year and they have gotten their renewal scholarship.
Could you please tell when I wil get the 2nd and 3rd installment.
