MakeMyTrip India — Refund issues during covid period

Dear sir,

We booked the following flights through makemytrip on 13/02/20 for two passengers

1) delhi to goa PNR K4KW6Q costing 8518
2) goa to delhi PNR A8JFTE costing 7792

Then the pandemic restrictions came into effect and the air travel was suspended

Now Makemytrip has imposed a cancellation charge of Rs. 7792 and refunded the balance amount but I never cancelled the trip. And they are not refunding the "7792" amount to me saying that the amount was imposed by Air Asia.
I have it in writing from me from Air Asia that they have not imposed any cancellation charges and refunded the full amount .
I don't know who is at fault but I haven't received my Rs. 7792

There are so many people with similar problem. The only common thing is Makemytrip. I think the company is making crores of money by duping customers like us
Please resolve my problem
I'll be highly grateful

Waiting for your reply
Kindly call back if possible
Regards
Ayush Agarwal
