GoAir — refund of my booked flight (pnr - f2r1rl)

This is to inform you that i have booked my flight on 10th of july 2020 from goa to varanasi on "g8 381 from goa to mumbai" and on "g8 349 from mumbai to varanasi". Pnr f2r1rl
But due to cancellation of flight from your side i have not been able to travel to my destiny. There is no refund option coming in your website. Only the "change booking" option was coming, which i could not do as i had to reach my home urgently. Also, no calls were picked up from your side at goair call centre. This is very poor service you are offering to customers.
So, its a request to you to refund my money as soon as possible.

Regards,
Vipul
