Re: AC of coach is not working since many days, but there is no action on the part of railways
This is a clear case of deficiency in service on the part of the railways. As you have already lodged complaints in the complaint book, now take up the matter with the Chief Commercial Superintendent of the Railway concerned to obtain refund. The matter needs to be followed up through the consumer fora, if necessary. RTI Act will not be of much use here.
Defeat is not final when you fall down. It is final when you refuse to get up.
