Golden Forests India Ltd — Payment of Golden Forest

I have been contacting Karvy for the payment of the below mentioned accounts. We had already received cheque against these, but due to the decease of the account holder we, as nominee, had requested to reissue the payment.

After number of phone calls and emails, the last communication I got in January this year that my documents have been verified and I'll receive the payment through NEFT. I have not yet received any payment.

Can any one please guide me how I can escalate this matter.
