GoAir — requesting refund

I had booked flight on go air flight g8 57 having booking reference jf9w4b, flight departure date was 27 march 2020
Unfortunately, because of covid-19 this flight was cancelled but i didn’t received any email or sms notification yet.
Two days before the departure date contacted customer care and they promised me, they will refund the amount. Still am waiting for the refund and now customer care number, emails even nodel officer, appell authority not responding,
Requesting to refund the amount as possible
And i don’t want to free rescheduling because i lost my job recently and most probably am not planning to go back to dubai
Kindly refund the amount
