GoAir — refund not sent

Address:

Bangalore, Karnataka, 560078

I had booked a flight ticket from ranchi to Bengaluru and the date of journey was 17th January, 2020.
2 days before the flight, i received a message stating that the flight has been cancelled directly by the airlines on that day and you'll be getting your refund.

After few days, the refund i received was 130 rs. I had booked the ticket for 4775/- and received a refund Only 130/-

The flight got cancelled and that was not my fault but still they are not sending the me my full refund.

Pnr number is PDKL3H
