[Resolved]  Yatra Online / Yatratrip.in — Didn't refund my full money

I booked my flight through yatra app. AirAsia cancelled my booking and generated full refund to me through yatra. But yatra deduct some convenience fees rupees 830/- and refund my remaining amount. If i cancelled the booking then I can understand this deduction but if airline cancelled my booking then y we should pay convenience fee to yatra. Y customers have to suffer due to airline mistakes.
