I booked a flight from delhi to sharjah for 20 dec 2021 on 20 nov 2021. With booking idNN7X6RR9AAR7F9S45764 . PNR NO BIYDMS in indigo. Than i changed the date via mobile app on 21 dec and i was suppose to get refund of 2797 which I have not received. Than i cancelled the flight on 8 jan and i was suppose to get refund of 10, 274 which also I have not received. It is showing on app that amount has been credited but it has not been credited to me. I am attaching my bank statement. Kindly help me get the refund.
