MakeMyTrip India — refund of cancelled flight of jet airways past 64 days

This is regarding my booking id nn[protected] of jet airways flight ticket for mumbai to singapore and return.
As jet stopped operation in april. I was informed that my flight ticket was cancelled. I had immediately initiated my complaint on 17th april'19. I had to book another ticket in place of this since i was given assurance of refund at the earliest.
It has been more than 2 months now but i have not received the ticket refund which is around inr 50, 000. Whenever i reach make my trip they tell the status is in process. They are telling the same from last 2 months. Jet airways sla for refund was 45 days it has been more than 60 days for my ticket refunds. Which should have been refunded by them. I asked them for the escalation mails or the communication they have sent to jet airways regarding my booking to which also they have not provided the details. I am now since last two weeks not able to connect to makemytrip customer support as well. They disconnect the call as soon as the line gets connect to a specialist. As a middle class person inr 50, 000 makes a lot of money. Please help me in this..
