Sahara Q Shop — not getting amount after maturity

Address:	500002
Website:	Sahara india q shop

We have visisted sahara india abids branch today to request the processing of a bond for which is matured in oct 2018 from 2012.
However they have rejected the request and asked us to covert the bond for more 2 years stating that they have deposited our amounts with sebi as per supreme court orders and we have to collect our amounts from sebi. But as their customers they will do this for us which take 2 years and when we said we will approach sebi and get the refund the they said it will take more 3 years to get the refund the amount from sebi.
They were giving multiple statement ls when we responded to their statements.
Below are few.
1. Our software has blocked and we cannot make the refunds for few years only for this scheme.
2. Sahara india is not liable to pay the refunds and sebi is liable because we have deposited the investment with sebi.
3. Sebi will verify and refund the amount but will take 3 years.
4. When we said we will go to sebi and request then they said deadlines is passed as per the newpaper shwed ny them and told we cannot go to sebi now and dint even told the procedure to reach sebi.
5. When we said the advertisement is about the sahara india real estate and not about sahara india q shop, they told all are same and hence cannot be refunded until 2 years.

Why should we wait for next two years when we have given our money on time.

Kindly help and resolve the issue.
