SREI NCD Call for Interest Credit

Hello, Received a call today from 79781 02560 informing I need to send a cancelled check copy and pan no. To [email protected] for them to remit the annual interest payment on the bond.
I have the NCD with zerodha and shouldn’t it be directly credit to the account that I have with zerodha was my reply, to which the person said no, I need to send them the requested information for the company to credit the annual interest. @nithin could you please confirm if I can share the information and why are these companies calling when the NCD is in demat form?
