[Resolved]  Indigo Airlines — Change of Flight Time

I had booked a flight from Chennai to Kolkata for the 10th April 09 under the Re1 Fare (Total Fare Rs 2225). The departure time stated was 1655. Later, when i checked the schedule for taking a printout, i found that the timing had been changed to 1945. This disturbed all my onward journey plans. When i talked to the customer call center, i was told that the Airline allows free of cost change in schedule only if the flight timing is changed by more than 3 hours(the change in timing here is 2hr 50min). Now, even changing the flight will be charged Rs 750.
This seems to be an ingenious way by Indigo Airlines to cheat its passengers as they have advertised Re1 tickets and will be charging its passengers Rs750 due to the change.
Surprising that such blatant cheating is going on at Indigo Airlines.
