MakeMyTrip — Refund not processed

My flight booked through makemytrip was not operational due to Covid19. I made a cancellation with the airline and applied to process refund through makemytrip. The airlines has confirmed that the refund has been credited to the agent. On the MMT App, it shows that the refund should reflect in my account between 4th and 7th Dec 2020. I have not yet received the refund and have no option through the App or website to address the issue.
