GoAir — i'm complaining about cancellation of flight without proper reason and rescheduling and cancelling the ticket without prior notice.

Hi, my prenst along with my younger sister have booked three individual go air tickets via yatra website on 22/06/17 from ahmedabd - bangalore, date of flying is 23/8/17. But yesterday (1/8/17) my father received a call from go air representative that the flight has been cancelled and what would you prefer rescheduling or refund as they already had their return tickets they couldnt take refund so he asked for rescheduling but when he inquired about rest two tickets which were booked individually, they said they would revert back but the representative neither confirmed his ticket nor gave any information regarding the other two. When we came to know that my father is having trouble in reaching them, we tried reaching yatra, the yatra representative didnt had any clue of flight cancellation and when we inquired about the ticket status they informed us that all the three tickets are cancelled. When we contacted go air, the representative didn't had any valid reason of flight getting cancelled that too 22 days prior to the flying. They told us that one ticket is on maybe rescheduled status but rest are cancelled. The go air people dont even bothered to call us to ask what we want whether we want rescheduling/cancellation, they just cancelled two tickets by their own. How can they do it by their own wish!! After explaining to two representative the whole situation they finally got my two tickets rescheduled with first one. Go air dont care for customer not even senior citizens, their actual flight was of 2 hours that too direct one but due to irresponsible behaviour of go air, now my parents are forced to travel for more than 6 hours that too by changing two flights.. I dont know what to expect from these people they think everything is realted to monetary compensation. My parents wont be able to due such long travel but their will to meet me after so long is strong that they dont have any choice but to travel by this flight. Go air authorities dont even bother to make their customers flight comfortable but try to make it worse. Highly disappointed. Wont recommend or travel by this flight if this issue is not addressed properly. Would definitely escalate the issue further.
