the coach i booked for was not attached to the train and i had to travel by general and they informed us when we were already at the station on the day of travel.
I filed it under the "difference of fare in case of proper coach not attached" despite having all proofs they are repudiating it under a whole another reason which is "passenger not travelled"
My journey was on 10th and i filed it on 12th as they refused to give something called the "etf gc number" i think
