As per the details provided above i booked a flight in air pegasus to travel from bangalore to kochi on 08.10.2016. Booking ID NF[protected] Flight no. Op 109, pnr no. MO87EH. The flight was canceled by the airline .The Airline had canceled the flight and the refund is pending from Makemytrip and airline.I got a mail from makemytrip stating that the flight had canceled and i will get a full refund. But later i got eticket from makemytrip for my travel and again i called the makemytrip and they updated that the ticket is not canceled and hence the refund is not processed.Here are my question
1. If the flight is canceled why a customer have to cancel the ticket and waiting for the refund (It should happen auto refund)
2. when i will get the refund?
3. is the refund will come with the bank charges also?(i paied through creditcard)

Request you to please refund the money
