MakeMyTrip India — Refund not received even after several calls

I did not receive refund for my flight booked against the Booking ID: NF[protected].
Entire trip was cancelled by the airline and I am expecting full refund as already raised the request.

Noone is available to answer the call when I try calling on the support line. They direct you to some link for refund status which is not audible clearly.Why is MMT trying to make people duffer who has booked the tickets through your portal ????

Please process the entire refund amount immediately.
