I had done a booking [PNR HSKTG] for Air India Flight AI661 for Sept 7, 2013 [sector Mumbai  Goa, 15:00 hrs] on June 14, 2013. I called the AI customer helpline [18001801407] for changing the flight from AI661 to AI984 [sector Mumbai  Goa, 5:15 hrs Sept 7, 2013]. The Gentleman changed the flight timings as requested and on inquiring did not suggest any additional payment for the change. On July 23, 2013, I was issued new [PNR YSQHS] for Air India Flight AI661 for Sept 7, 2013 [sector Mumbai  Goa, 15:00 hrs]. The reason being the ticket was cancelled by Air India for non-payment of penalty charges. On the call on June 14, 2013 I was not informed about any charges and this has been confirmed by Amrinder a supervisor in the call centre at Chennai [18001801407] that it was a mistake on part of the agent who made the changes on June 14, 2013 that he did not inform. The Airline is blaming the booking agent [Makemytrip] for opting for refund of the ticket instead of open for use
