Indian Railways — horrible 3ac coach

We travelled from tirunelveli to mumbai on 23rd july 2017. We had booked caoch in 3rd ac, b1 seat 9 and 10. The coach was third class and horrible. It did not feel like an ac coach. It felt like second class with ac. There were coakroaches, seats were dirty, windows were foggy all the way. Curtains dirty. Worst experience ever. Please dont waste our hard earned money this way.
