Sahara Q Shop — mature amount not given

I have invested in nirman bond in the year 2010 and when this plan got matured, the sahara official did not paid the matured amount and instead re-invested the amount to sahara q shop plan-h. Again when q shop plan got matured they did not paid the matured amount and re-invested the amount in saharayn universal multipurpose society limited (Super bb) scheme. The same thing happen for my another investment where they have re-invested the whole amount from sahara m-benefit monthly deposit to sahara credit cooperative society limited.
Now sahara official are not giving the matured amount from sahara credit cooperative society limited and saharayn universal multipurpose society limited (Super bb) scheme.

Kindly help me.
