MakeMyTrip India — Delay in Refund Processing

Hi,
I made a booking through MakeMyTrip for a trip from Toronto to Delhi, Date of flight was 15 Jun 2021.
I cancelled the flight on 12 April.
First, makemytrip didn’t apply for refund untill 19 May 2021, After my continuous calls for a month, I contacted them for refund. They start the process.!

Then, no follow up has been given to me and taken from the airline regarding the delay of the refund.
It has been September now, my refund of Rs 47, 960 is still not processed
There is no support from MakeMyTrip. No feature on the app to raise the request/ complaint
