MakeMyTrip India — Refund for my flight ticket with Booking Id: IN1B[protected]

I booked a flight on call with MakemyTrip call support. Due to travel ban, flight was canceled and I couldn't travel. I talked to customer support before the departure date and they said that I can take refund or reschedule later. But now I am not able to connect to them through any medium. There is no reply to mails.

I have my booking confirmation receipt.
