MakeMyTrip India — Refund not received since 21 days

I booked return flights from New Delhi to Leh in May 2023 through Make My Trip but couple of days before the flight, the flights were cancelled from the airline due to operational issue and I submitted refund request on Make my Trip. The refund request were accepted and but it's been more than 21 days that I've not received my refund. There is no further communication from Make my Trip and no update on it as well. Please help me get my refund at the earliest. Thank You!
