Nism - Not giving me my certificate and not responding to my issue

I've given nism Mutual fund Distribution part * exam on * September ****.it was an online mode due to the pandemic situation.. I've given my exam through my friend's laptop as I don't have my own...at the time of exam..as I live in * rk i had given my exam in kitchen...and at the time of exam idk why my exam has been terminated..but during the terminal I've completed my test in half of the given time..and after that they directly prohibited me from giving any exam..after my objection that they can't prohibit me without giving chance of hearing they decided to arrange hearing in that also they send me text message but they didn't provide me link due to which i was not able to attend it..after that in hearing it was clearly proved that I've not done any kind of cheating nor I've tried just because I live in one room kitchen i can't throw out my family members in that pandemic situation... plus I've completed my test in half of given time..if i was trying to cheat then how become i can complete my test..and after that they appointed their one of the member Ms Nidhi Murdia to whom i tried to explain my situation that i can't appear for re exam as i don't have my own laptop and at that time offline exam was not possible...and she didn't responded me and successfully wasted my time, money..and for that issue I've also called to Nism helpdesk for atleast * times but they can't help me and I'm totally unsatisfied with the decision which is very unfair for me..so it's my humble request to provide me my certificate. Firstly they were not responding at time.. and they don't give chance to the candidate..and after complaining in Nism helpdesk they firstly didn't responded and after that they said it's old case..we can't do anything.. I've given exam fees and appeal fees too..i want justice.just because I'm candidate I'll not scared.. I'll raise voice against Nism team and their management...there are so many complaint against Nism on different platforms and yet not solved.. and i want compensation for my wastage of money and time ..and I've all proofs of emails and call recordings.
