Flight got cancelled due to corona virus issue.

The total amount paid is inr 54488 and refund amount mentioned by goibibo is inr 2892.
As the flight itself is cancelled due to the corona virus, as a customer i should get the full refund.
Kindly consider my complaint and help in getting the full refund from goibibo.
The below is the mail from goibibo on refund.
Invoice of ticket is attached as attachment.
