Dewan Housing Finance Corporation [DHFL] — pmay subsidy not received.

Have an on going loan from dhfl from august 2018. I still have not received pmay subsidy till now. On asking dhl they just vaguely say that my file has been submitted to the NHB there is delay from govt not our side.
They are not even providing me any proof/ acknowledgement that file has been really submitted or not.
Please look into this matter. They are blaming govt. for this. I have asked them to follow up with NHB there is no response to this further.
