Easemytrip has not been Refunded my complete amount(10741) as flight was cancelled due to covid and they are deducting convenience and service fee which should not allowed in case flight got cancelled. However Airasia has refunded full amount(10741) to ease my trip. Ease my trip only refunded 7594 and difference amount 3147 is still pending. Kindly help ?
