@Akhil thanks for the kind words. Now that you have Reliance PP, to retain them till they convert all Reliance PP to Reliance Fully Paid shares you will have to pay the remaining installments of Rs. 314.25/- May 2021 and Rs. 628.5/- Nov 2021.
These payments will not go to Zerodha nor through Kite. The payment will have to be made via the registrar’s (KFinTech) website to Reliance. You will recieve the notification from them closer to the payment date.
Hope this helps!
