IFCI — Unable to redeem IFCI family and education bond

I have the IFCI family and education bond that had been issued on 6 September 1996. It has already been matured. I had approached IFCI to get the bond redeemed but they informed me that they had transferred the amount to Investor Education and Protection Fund. So I sent a letter to the Finance Manager of Investor Education and Protection Fund on 23 March 2010, Dy. No. 1057; but in vain. Till now I couldn't redeem my bond. Kindly help.
