ONGC — Regarding ONGC OBC scholarship renewal

I'm Karishma Phukon, with ACK no.ONGC[protected], a scholar of ONGC OBC scholarship, I've not received my renewal scholarship amount as all of my friends got it on time I've called to this number [protected], so many times, first time it got received and I was told that I'll get the money within 7-10 days but it's about to be 1 month.
And a note to be added that my account was is UBI bank but it got changed to PBN i've mentioned that too in the form so that it doesn't creates any inconvenience, but still got no response till date.
I'm going to be admitted to PHD program now I needed that amount.
