National Institute Of Securities Markets [Nism] — NISM V-A certificate is "On Hold"

I've completed NISM V-A exam through "Exam From Anywhere" online mode.
Followed all the instructions and completed the entire exam and no where I've been interrupted or questioned by the examiner. Initially I've been asked to show 360 degrees of my surrounding, I did that too. And it was of total silence.

If there were some disturbance or doubts, they could have interrupted in between why prolonging till this?

I'm not sure why they have put my certificate on hold. I've contacted on email but the exact reason was not mentioned anywhere and asked to file a appeal paying 590/-
