IFCI — Ifci family bond fraud - folio no 5590566

Address:

9 Shashank row house near vaishnodevi heights canal road Jahangirpura surat 395005

My father invested in family bond of IFCI on 6 sept 1996
As per the bond, there are multiple redemption dates where we can redeem the amount early if required.
Today I called customer care number of IFCI and I requested him for redemption.
As per redemption date 6 sept 2019
My deemed face value is Rs 170000 but the person who attended my call he told me that I can get only Rs 13680.
Please help me in actual value redemption as mentioned in family bond.
