National Board Of Examination — DNB final practical examination

I passed theory exam of DNB Neurology in June 21 and failed in practical part. Before my result was declared I applied for DNB December 21 session and my application was successfully registered in NBEMS. I am eligible for the 2nd attempt practical examination in Dec 21. But I have not received any admit card or communication about it. I have already sent communication to NBEMS about it but they only reply me to see the information bulletin of the examination. After that I sent my message to the grievance redress forum of NBEMS but they are not responding.
