HappyEasyGo — Refund amount pending

I had booked a flight with cancellation protection through happyeasygo from Patna to Bangalore flying on 3rd September 2022.
I've cancelled the flight on 1st September 2022 and I was said that I'll get the refund amount in next 10-15 days. I waited for 15 days and again checked with their customer care then they told it'll be refunded in 45-90 days. Even after completing 90 days I didn't get my refund.
Now, they are not replying to my email and also, their helpline numbers are switched off.
Order ID:[protected]
Ticket Fare: INR 9279

Can you please help in getting my refund amount.

Regards,
Uttam Kumar
