Karvy — I havent received my sold share amount.

It’s been 13 months from now I sold share in October 2019 worth of 62433.68/-, it’s November 2020 the amount is not credited yet, I went to the Rajindra Place office & Connaught Place office many times but they’re saying no updates & Unless providing the interest on my money they are deducting few amount every month from the balance of 62433.68/-. The company is not in the mood to refund and checking up the patience of a lower middle class person. If I didn’t get any positive response from the company here then there is no other option, I have to reach out hon’ble Supreme Court.
Here is my Details:
