Hello. This is puneeth. I booked 17 tickets of flight g8-508 which was scheduled at 15th jan from cochin to hyd. I did three transactions for booking 17 tickets.
Here are the booking reference numbers

I got fed up with bad response of customer care. I mailed to feedback team but in return i haven't get any proper response. And as a result we had to book flight tickets of higher cost at last moment which costed 1700 more than go air flight. No matter what the reason might be either technical failure or something else. But its their responsibility to arrange alternate travel. We suffered a lot including 3 kids. I just want my money back. I request concerned authorities to refund money asap.
