Yatra.com — Credit shell and refund status not shown on website

I, geetika panda, booked a flight for myself from blr-ccu for 2nd april for flight 6e 433 in an indigo fight. A refund of inr 4909 only is being shown against my pnr on indigo website, while the booking was done for inr 5083. Also i am unable to use this credit through indigo website since it is asking to contact yatra, and yatra is showing no option of booking flight using this credit. I have another booking for indigo flight 6e 691 from ccu-blr (Inr 3034) for which too the same issue is being faced.

Please refund the full amount of inr 5083 and inr 3034 and specify the exact procedure of booking the flight using credit shell.
