I had purchased 6 tickets from air pegasus through make my trip, booking number
Nf[protected]. The flight was canceled by airpegasus due to technical fault. So i had to book in the tickets in a different airlines. As the flight was cancelled by air pegasus in last moment i was assured of refund. I had to go through lot of difficulty due to canellation and till now i have not got my refund.
Got a reply from make my trip, that despite their best efforts air pegasus has failed to refund and i should seek the refund directly from air peggasus. Its now 1 year i didnt receive the refund
