National Institute Of Securities Markets [Nism] — Hold on certification

I gave NISM research analyst exam on 30th April 2022. After passing the exam I received an email (It is observed that your conduct during the said examination does not adhere to NISM''s Policy on Use o[censored]nfair Means, Cheating, Impersonation, Forgery during NISM Certification Examination, CPE and eCPE). My certificate has also been put on hold and while inquiring I was asked to raise an Appeal which will be costing Rs590. I am not sure for spending another Rs590 on some allegations. I did whatever and whenever asked during the exam. If I am found indulging in some unfair practices, I would ask to email me with the proof so that it can be easy to settle.
