MakeMyTrip India — Not getting refund which I booked from makemytrip

Initially i have booked a connecting flight from delhi to bangalore via hyderabad for 17th june, 2020 with ticket no:[protected]. Later airline cancelled these connecting flights due operational reasons and reissued new direct flight with ticket no:[protected]Attached below). Further airline also canceled[protected] this ticket.

Now i want to claim refund for this ticket, i tried to reach makemytrip as well air india customer care so many times but not getting a proper response.
Makemytrip customer care agents have asked to take help from air india for a refund. But air india customer care agents have asked to take help of makemytrip to initiate the refund then only air india will provide the refund.

I am totally fed up with this process.
Please initiate the refund process with air india.
