MakeMyTrip India — Refund not done for cancelled airlines ticket

With reference to my Eticket NF[protected], I would like to mentioned that I booked VISTARA Airlines ticket through MAKEMYTRIP on 12.01.200 for journey from Delhi to Mumbai on 16th May, 2020. But, due to Covid Lockdown, my flight was cancelled. As per VISTARA Airline refund has already done last month, but still I have not received refund from makemytrip. I humbly request to please help me in getting the refund at earliest possible time
