Hi @aLL_MoDe_vishal_raj,

As we already informed you, the rejection is from the Exchange and it could be because of KYC validation pending.

Please check this article and follow the steps carefully to complete the KYC validation: What is the process to verify KYC details (email and mobile number) registered with KRA? - Upstox Help Center

Once you raise a ticket, let us know the ID and we will get in touch with you soon.
