Cleartrip — Case ID : 16369409 refund Issue ongoing for a 2 months

Address:

Gurugram, Haryana, India

I had to cancel a BA ticket last year in Jan with covid case rise and local govt regulations for health care workers (spouseworks in healthcare) and 4 year old child travelling with me.
Now when I try to rebook price is 1 lakh more for penalty charge it seems.
Why is penalty fees for an existing customer to rebook a ticke due to covid which is not in my control .
When I call there is never a supervisor in the team and they say they will call me back but no reply every 2 days I am calling back on ISD charges .
Any help is appreciated.
