Air India Express — Refund of booked tickets

I booked a two way ticket in Dec 2019 to travel in July 2020 from Doha to kannur. But due to pandemic flights were cancelled and meanwhile i lost my job in doha and repatriated back to kannur on Aug by Indigo flight. From june i am sending mails to customer care Air india express about refund but the reply comes as change your travel plan suggestion when i say i lost my job & returned. So they are not reading our mails just copy paste a standard reply and sending.
Please arrange for refund immediately
