[Resolved]  Yatra Online / Yatratrip.in — Unable to use Airline credit

Due to Lockdown, my Yatra flight bookings were canceled in the month of June and the amount was credited to the Airline credit.
I had several bookings which costs Rs.37677 in total which is stored ad Credit shell.
And per airline rules, I can use that credit shell within a year.
Now when I am trying to book flight tickets from yatra, I am unable to use Airline credit.
Instead, it prompts me to claim refund in which Rs.800 will be deducted per person.
Why should I claim refund when I already have an Airline credit shell which can be used to book tickets.
This seems a complete trick by Yatra to fetch money from the customers.
