Nagapattinam Sivasakthi Chit Funds Private Limited - Savings and FD Amount Not received

I have both Savings account and Deposit accounts with this company. (Nagapattinam Sivasakthi)
My Savings Account Balance is Rs. ******/- I have been trying to withdraw my Savings account balance since *st June **** but the bank is not giving my account balance.
Additionally, I also have fixed deposits here with monthly interest payout opiton. But they stopped paying monthly interest also since June ****. I have deposited my entire lifetime savings with this bank and was running my family with the interest amount i used to receive. Now i am not getting both the interest amount and the principal amount and suffering a lot without having money even for the basic needs.
I have visited their office multiple times requesting my savings and Fixed deposit amount but they dodged every time.
