MakeMyTrip India — Refund request agsinst cancellation of flight

Please refer to make my trip Booking ID NF[protected].
I have booked Air India Flight AI-469 from Delhi to Nagpur on 31st Oct 2020. Airline PNR is 098-[protected].

Basically, I was traveling from Wuhan (China) to Delhi by Vande Bharat Mission Flight number AI-1315 dated 30th Oct 2020. Then I have connected the flight to Nagpur. The flight from Wuhan delayed departure and reached late to Delhi on 31st Oct 2020 morning. Once I reach to Air India check-in counter they refused to give a boarding pass and asked to go to Air India ticket booking counter to cancel the flight. After reaching to their office AirIndia gentlemen listened to my story and canceled the flight ticket and issued me a full refund document stating that I need to show this document to Makemytrip to enable them to release a full refund. This document is attached for reference.

I raised the full refund claim with Makemytrip against claim reference number[protected] . Since then I am chasing them for a full refund, but unable to get it. They are saying Air India rejected the claim. When I contacted Air India, they said the claim is open. I have attached an email communication from Air India where it is clearly mentioned "Your ticket status is showing open for use"

I have written many emails to Makemytrip, talked to their customer service representatives, but there is no use.
Please help me out from this situation as MakeMyTrip is fooling me.
