MakeMyTrip India — Refund stuck with Makemytrip

I had booked tickets Goa Air -G8 247 for 4 people from bhuvaneshwar to Mumbai on 13 Jan 2020 for travel on 19th APRIL 2020 . For this i received the refund of 926/- only .But the actually the ticket was reshedule for 7 Feb 2021, which was later cancelled.
For this i received the confirmation mail from Go Air support about the refund of 5712 /- .I had forwarded the same to makemytrip support group but they have not responded.
Below is the Go Air support team mail
