Sahara India Pariwar — Back my money

I had 1 bond in name of chetna patel of sahara special scheme which has matured on 20 april 2020. But the vapi branch of sahara is not paying the amount.
The branch manager is declining to pay the matured amount and he is forcing me to renew this for again 3 years.
I have an urgent requirement of money.
Please resolve the matter otherwise i will compliant to sebi, or any other portal.

Regards,
chetna patel
