I brought kingfisher airlines stock few years back and I didn’t notice the stock was suspended last year because of defaults. I have only 10 shares in hand and status is on HOLD. I couldn’t sell it from my Demat account and I want to pay annual service charge (~900) for just 10 rupees stocks. I moved to Zerodha and using it for all investments. I want to close my old Demat account (hdfcsec) . can you please tell me what to do?
