Sahara Q Shop — maturity amount refused to be refunded

Sir,
I have invested in "sahara housing investment corporation limited" in 2012. Without my permission or any prior notice my investments were transferred to "sahara q shop unique products range limited". Now the maturity date has been reached and the branch manager refused to refund the money back instead he is asking to extend the plan for another 3 years in "sahara cooperative fund". I am really in need of that money. I want my money back instead of approaching for a new plan.
Kindly help me to get the money refunded..
