Ixigo — Full refund not initiated as per policy

I have booked a round trip from new delhi to patna under ixigo assured.
I have paid a total amount of Rs. 6585 and as per cancellation policy I was supposed to get a refund of Rs. 5587 .

But I today I got a msg from from ixigo that a of refund of Rs. 1224 has been initiated.

I am attaching the screenshot of the price breakup.

Kindly look into the matter and generate a refund as per cancellation policy.
