GoAir — Regarding my cancelled ticket refund

I booked two ticket from Varanasi to cochin last November 2020. the flight got cancelled itself and it was informed just the day of travel only and after cancelling the tickets I requested for refund and till now I haven't received my cash back/ refund EVEN AFTER REPEATED ENQUIRIES and calls goair people doesn't have a responsibility to refund the cash. here also I'm adding my FLIGHT NO: G8-404 ON 5TH NOVEMBER. PNR I55R3C.

THE WORSE CUSTOMER SUPPORT. IRRESPONSIBLE FLIGHT services . I advice everyone not to choose this flight as we normal people go for a cheaper flight.
