Sir,
My family travelled from ernakulam to patna on the 13th of july 2106 and we sufferd a severe rat trouble during the travell of 3days.

My luggage was severly damaged by the rat and caused me a lot of financial trouble. Despite registring severe complaint no action has been taken yet.
I was travelling in patna - ernakulam super fast exp (22643).

So kindly do any help that can be done.

Yoours faithfully
Ajith v saju.
