Ibibo Group / Goibibo — Did not receive a refund yet from the company

I had book a flight from Paris to Munich and Munich to Mumbai from Goibibo and the flight was cancelled due to lockdown and the plane did not take off. At first, we were informed that refund will be granted but its been more than a year no refund has been given untill now. I have also sent them a legal notice but they did not respond to the legal notice. I am attaching the ticket in here.
