Sahara India Pariwar — maturity amount not given in time

Sir, we have made fixed deposit with two sahara't' bonds in my son name in 2004 for rs 10000 and rs 15000. and that maturity date is january 2017.
I have request, withdrawal for that amount in sahara branch anjora durg(chhattisgarh). but they not pay a single rupee. they say you come after two month then you come after 20 days then you come 1 month then you come after 15 days then he say we have not sufficient fund. for the past 6 months that have been fooling us round and round.
please do the needful action.
