Southern Railway — unreserved people in reservation compartment

We booked ticket on s9 coach-pnr[protected] from ern to cbe on[protected].
There are lots o[censored]nreserved people get in to the coach from ern station and not even have a space to keep a leg on the reserved coach.
The terrible scenario is all bathrooms are occupied and locked from inside by the unreserved people. Ticket examiner came to the compartment and the situation not even changed. I was struggled a lot with my carrying wife in the coach. The situations seems to be like train ticket examiner escaping from the coach with his life. It was the most worst experience i had in my life. I wrote this complaint due to this situation should not be happened to anyone in future.
