GoAir — flight cancelled but pnr credit wallet is showing blank

Address:

Ghaziabad

I took Goair flight so many times but this time i really faced deep problem and difficultly just because of chosen you.
I book round trip from srinagar to delhi 6 june 20 and back to srinagar from delhi on 15 june 20. I reached delhi comfortably but my return flight which was scheduled on 15 june was cancelled without prior information and intimation. I booked another ticket for 1july2020 but again my flight was cancelled that is so ridiculous. As per your and govt policy that amount will be safe till 1year, if flight was cancelled due to corona Now i want to book my ticket from srinagar to delhi but not able, when i reach payment page no balance show against my PNR S8ZL6Z as per site and govt policy in corona my pnr is protected.
Now tell me how can i rebook my ticket.by using my unused ticket balance

PNR no.-S8ZL6Z
Journey delhi to srinagar
Flight cancelled Date 15 june, 1july 2020.
