MakeMyTrip India — Half of the refund not received - COVID refund

Hi,

I booked a round trip ticket in MakeMyTrip. They refunded due to COVID cancellation to the makemytrip wallet. I selected in the app to transfer it to my account but I did not get. After months of follow-up, I got half of the refund but they did not send other half of the money.
Even after so many emails and calls and online requests. Kindly help.
