I had a lot of cancellation, refund issues, during one of my vacation to Orissa, and I used yatra at first but they were just rubbish. I then used cleartrip app to book everything right from flight to hotels and im happy with everything they have to offer.
the booking was easy and also the refund procedure was quick, got my money back quickly.
the customer service of cleartrip is the best ive seen. they have answers to everything.
all of my bookings are now done via cleartrip only
