MakeMyTrip.com — refund of cancelled flight

It's been more than 2 weeks since makemytrip themselves contacted me that airlines has cancelled the flight due to operational issues and yet they have not processed my refund
They are not reachable at all: not on mails, phones, web forms and the worst of all is their chat. There is no single live agent for support.
I understand that this is a difficult time for everyone, however, it wasn't the case last week. It's pure torture now
