[Resolved]  Ibibo Group / Goibibo — rescheduling of flight not done

I booked a flight (Hyderabad to paris) i wanted to reschedule my flight since it had long layover at jeddah. I told them to reschedule it with a flight having less layover. I called them 100 times and requested again and again but in vain. Everytime they assured me that they will do it but nothing happened.
My money is stuck since the flight is non refundable. This is how goibibo makes money? Horrible customer service. Full of liars. I am still waiting for solution. I will never make a mistake to book anything from goibibo.
