MakeMyTrip India — not refunding amount for flight cancelled by airlines

My indigo flight from kolkata to pune on aug 17 2020 got cancelled by the airlines due to the covid restrictions in west bengal. I was travelling from aizawl to pune via kolkata, but since the second flight got cancelled, i also cancelled the first flight with the airlines, and indigo have confirmed refunding the amount to makemytrip.

However mmt hasn't refunded me the amount, also it does not allow me to raise a refund request saying that the status of my flight still shows active. How is that even possible? I am attaching the cancelled itinerary from indigo for reference showing the refund amount.

I had also purchased an insurance on this flight, not sure how that is of any help.

Also, it is extremely difficult to contact mmt support. I have been trying for many days now, so i have to finally write a complaint here. Thank you!
