Union Public Service Commission [UPSC] — Complaint against controller of examination o[censored]psc centre

Dear sir,
I have complain regarding UPSC exam 2022.
My wife was aspirant and had filled the form. Her residing address was Bokaro and centre provided AT SP MUKHERJEE UNIVERSITY RANCHI, BLOCK B.
we had approached anyhow at centre at 9:15 am at block A( not mentioned and not display)
There some person told that block B is some 300 m away. We then approached at block B at 9: 23 am. Where centre was locked and there was not any display that block B is this location.
Police authorities not allowed us. No any representative of examination was present.
We appealed to have conversation regarding allowing but no any person took pain to come and convey and listen our appeal.

This is totally false and totally unfair. They had played with the career of any women aspirant. She had last attempt this time.

We want to lodge complain against controller of that UPSC exam centre.

Thanks & Regards.
