MakeMyTrip India — Refund not received... it's been more than 7 months.

Dear Sir/Madam,
I had booked my air tickets for three people with MakeMyTrip for a trip from Toronto to Mumbai on August 03 via Delhi on Air India. This flight was cancelled by the airline due to COVID-19. MakeMyTrip has raised the refund request with the airline. I was told that it will take 90-120 working days to get the refund. It is now 7 months. After multiple follow ups with the travel agency I am still awaiting the refund and getting the same response that they are awaiting refund from the airline.
Here is my booking ID: IN1B[protected]
Passenger Details:
• Neelam Pankaj Shah
• Shweta Sagar Shah
• Ayaan Shah
Refund application #s: [protected], [protected], [protected]
Ticket amount: 88, 902

I am not getting any new update from MakeMyTrip or Air India.

Will really appreciate the support in speedy resolution of this.
Sincerely,
Sagar
