Kotak Securities — I am compailing about option trading

Hello sir, My kotak securities mobile number ki [protected], i bought Bank nifty 43300 ce at the price of 134, but my order is not executed. after sometime price falls below the price of 134 but still not executed. I called customer care many times but not received the call. I tried a lot, due to no response from Kotak securities, i am registering a complaint in consumer complaints. I want Kotak securities to compensate me for any loss i may have suffered due to the malpractices of Kotak securities. Thank you.
