Sardar Sarovar Narmada Nigam [SSNNL] — Sardar Sarovar Narmada Bond Redemption Process

Dear Team,

I am Vishnu. My father in 1995 has purchased a Deep Discount Bond.
The amount has matured in 2015.

The folio number is : 334877 and certificate number is 313981.

I tried calling the customer care number more than 100 times for the last 1 month, but no one lifts the call.

Can you please help. I want to know the process for redemption

Regards,

Vishnu Teja V
