Sahara India Pariwar — Amount due on maturity not received

My mother Manju Bathwal has opened 4 RD accounts with Sahara Credit Cooperative Society Limited. Two RD accounts were started on same date 01/12/2012 and the remaining two were started on 31/05/2012 and 30/08/2012 respectively. The RD accounts are named as Sahara M. Benefit and they have a fixed term of 5 years. These accounts were matured in year 2017. From that year till now in present day 26th November 2020 only an amount of rupees 15000 is received.
We have invested a huge amount in this company and now we are suffering because of it. We have also invested in Sahara Q Gold Mart Limited on 07/09/2012 in the name of my mother. That too is matured on 2017 and still not received. I am complaining this matter to you to look into the same and give me an immediate response. The above mentioned RD account numbers and gold certificate shall be attached for further details.
