MakeMyTrip India — Airlines refunded money not given my Make my Trip

I booked flight tickets for four passengers to and fro from Mumbai to Kolkata and another ticket for one passenger from Mumbai to Vadodara through Makemy trip paying through my net banking bank account. The ongoing flight from Mumbai to Kolkata on 4th May, 2020 for four passengers was by Indigo airlines flight, 6E-374 having PNR no OJKDSJ and the return flight for same four passengers on 9th May, 2020 was by Spicejet Airlines flight, SG-6422 having PNR no ODVRQD. Another flight ticket was for one passenger from Mumbai to Vadodara on 9th May, 2020 by Indogo Airlines flight, 6E-5342 having PNR no VM7P6Q.
All the flights got cancelled by the the airlines due to government guidilnes because of Covid, I received a SMS from Indigo for the refund provided to the booking agent. I tried to contact Makemy trip but failed to contact them. I called Indigo airlines customer care and understood that they had refunded the money to Makemy trip on 21st June, 2020 for both the indigo flights due to the cancelled flights by them but Makemy trip has not yet refunded the money to my account .
