Sahara India Pariwar — Sahara is not giving maturity amount

I have invested in Sahara 9 years back, I was to receive the amount in February 2020. I have not received any amount yet, nor any confirmation as to when can I expect the amount. I have been continuously trying to reach out to people in my city who are associated with sahara, they themselves don't know anything and are just making excuses. I want my full matured amount from the company including all the taxes as promised or stated in the documents as soon as possible.
