Kotak Life Insurance — I want to deactivate my agent code

I am Subhodip Pandit and i want to deactivate my agent code from IRDA PORTAL. I have sent mails to IRDA however I did not get any response from there. My agent code is KLI60941112 and my Pan no is DBVPP8608C. I got a job in an insurance company but am not able to join there due above mentioned issues.
Kindly help me to cancel my agent code.
I'll be obliged to you.
