Sahara Q Shop — refund of payment

I had deposited an amount of rs.41750 as advance for sahara q shop goods (Exist) plan h on 6.6.2012. The maturity amount of 98112/was due on 6.6.2018. But now the branch manager says me either to convert the amount in another plan for two years or surrender to him original certificate issued to me by sahara at the time of deposit. He further says that he would send the certificate in original to sebi for payment. As these are neither bonds nor shares i fail to understand why he insists me to hand over the certificate to him for his onward submitting the same to sebi. As i urgently require money, kindly arrange to give me maturity amount
