MakeMyTrip India — Pending Refund for Flight cancellation from Past 2.5 years

This is regarding the refund of the flight ticket Cancellation (Booking ID -NN[protected] which was made on April 20, 2019 from Amsterdam to Bangalore. I have made several calls for the same to get an update and the response that I had received was that it would take around 30 to 45 days for the refund to be processed. As of now it has already crossed 2.9 days and still I do not see any action taken care from your end. I still don't see any action taken from 'MakeMyTrip' side for the same and have the worst customer service ever.

Amount expected to be refund is around 18000 INR.
The Jet Airways flight from Amsterdam to Bangalore got canneclled as they stopped the service. My friends who have booked directly with Jet Airways have received proper refund of their tickets. I was betrayed by MakeMyTrip and they still vague, lame reasons and stop the refund process. I have booked the tickets from MakeMyTrip so its their responsibility to return the money when the flights gets cancelled.

Please help with this request. I have been following up on this for more than 33 months now and exhausted. this is my final attempt and if this doesn't work I have look forward to take this taken care legally.
