Indian Railway Catering & Tourism Corporation [IRCTC] — not provided information about route change.

I booked seats on train no. 17624 more than a month ago, receiving 2 confirmed seats. On boarding today, we discover that train route is changed to go via madhya pradesh, skipping the destinations for which we hold a confirmed ticket. No notification, no email, railways prefer to surprise people, advising us to get down at an unknown station and wave parchment in front of station master to recover the sum for rest of journey. You can make the rest of the journey with the spare change. It is already presumed that people of india have worthless time to spend waiting at stations, we contribute nothing and we should be happy and grateful if public services screw us over. I do not ask for compensation, just the basic decency that railways stop behaving like spotted hyenas and give a damn about derailing the country's resources.
