Airasia — refund of flight ticket because of coronavirus lockdown

I have booked airasia flight no. I5769 from ahmedabad to kolkata for 11.35pm on 20th march, 2020.
Please find the attached ticket for your reference.

But the police at ahmedabad didn't let me go to airport as all routes are closed towards the airport because of lock down.

I am unable to cancel the tickets also since it says non refundable.

But it is not my fault. I will like to have full refund of it
