MakeMyTrip India — Refund not received for international flight booking

I had booked a fully refundable ticket from New York to India which I had to cancel last minute because I got covid. Since this is a fully refundable ticket, I should get my full money back. I have submitted my covid certificate to makemytrip as well.
The refund has been stuck for over 2 months and everytime I call, the makemytrip representative says that the airline has to approve it. I even called the airline directly one day and they said that makemytrip has not raised a request yet. I am soo tired of calling makemytrip everyday. I’m desperate for this to be solved.
Here are the flight ticket details-
