Dewan Housing Finance Corporation [DHFL] — no response from dhfl on part disbursement

It's a very disappointing experience with dhfl and in spite of mailing to [protected]@dhfl, nodal officer and even ceo is not helpful to get my part disbursement and the branch sales manager says it's on hold with a reason that dhfl is facing problems. It's been more than 2 months.

While the builder is putting immense pressure and has been talking about cancellation of entire transaction.

Who should be held responsible for this?

I have mailed more than 10 times along with all the details, screenshots etc.
