Ixigo — refund amount of my cancelled flight booking

My booking was cancelled due to covid pandemic,. You assured my flight booking is safe in credit shell when i wanted to redeeem credit shell, after 3 days of patience you said airlines wanted to refund me. I agreed and today i got a refund amount of 4951 for my booking amount of 6271 and credit shell amount of 5708. Is this some kind of joke why i got less amount? I am not going to tolerate this. Refund me compeltely other wise i am going to complain in consumer court
