MakeMyTrip India — Problem with the refund

I had made bookings in the month of March from Chennai to Washington Dulles. The flight got cancelled due to the pandemic. I requested for a refund, as my flights were canceled. The status of the refund still shows as Refund process delayed expect refund by 05 dec - 25 dec. I have been getting the same information for the past 4 months with the different date as refund date. I have been calling the customer support and has been on at least 50 calls trying to explain the situation and no luck. MakemyTrip has changed its customer service model and now I can't even call a phone number to talk to their agents anymore. I have exhausted all my options to get the refund, hence using this channel.

Qatar airways confirmed that they initiated the refund from their side. So I am not sure why this is taking more than 9 months to refund.
