Air India — refund of flight tickets due to covid-19

I booked the air india flight tickets from delhi - narita (Tokyo) last year from paytm for the travel period 27th march - 5th april, but due to lockdown in india, all flights were cancelled during this period. Now, i am following up with air india/paytm for the refund but none is them is responding properly.

I talked to air india agent on 23rd march regarding the refund and he promised me that i will get the full refund with next 15-20 days and they sent the remark to paytm regarding that. But now air india is denying for full refund. They are saying me to reschedule which is not possible as i am not sure of any future trip to japan.

Please find the details below:

Booking reference: rm20no, airline: ai/jlv7w
