Ibibo Group / Goibibo — Non-received of refundable amount

Dear Sir/ Madam,
I booked indigo flight ticket from Kolkata to Bhopal via New Delhi PNR EF92NV Flight No. 6E-966/6E-2022 for September 16, 2020 through through you. However, the airline resceduled the flight via Lucknow and caused me some problems and I changed flight to 6E-434 direct from Kolkata to Bhopal since I availed flexi fare facility. As a result an amount of Rs. 1641.00 was refundable to me. Un fortunately I am yet to receive the amount. I therefore, request you to do the needful to refund the amount to my account at the earliest. Revised fare summary is given below.
With regards,
Arun Roy
