I had very bad experience at yatra.com.
booked a mang-delhi ticket, via mumbai. they called me a few days before the departure date, and told me that the flight is cancelled and offered me either a full refund or re-book thru their bangalore flight. I opted the second.
only after a month of journey, I realised that refund was not made. I contacted yatra, and they asked me to send a stamped ticket. I had to make a 3 hour journey(100km) to mangalore to get it stamped, thy said they sorted it out, but still refund was not made.
after this I made innumerable phone calls, which are reponded very poorly, sometimes they act as if they dont know even english. I got my ticket stamped 3 times. I got assurance from the king-fischer that I deserve a full refund.
it was one year ago. till date I got only rs 4000.- out of 14000 that I deserve.
