Goibibo — Refund not received(flight canceled by SpiceJet)

I had booked the SpiceJet flight for 26th October 2020 from Jabalpur to Bengaluru (PNR: JDVWUD). But on 18th October, I got to know that the flight was canceled by the airlines. I booked the tickets for INR 25, 276, but the refund amount that is being shown on the Goibibo refund is INR 24, 072.
This shows that the convenience fee that was charged at the time of booking is shown to be deducted from my refund. Since the flight has been canceled by the airlines and not from my end, I wish to know why the convenience fee is deducted from the refund.
I had submitted the refund request to Goibibo on 19th October and then I received a mail about refund processing. It shows that the refund would be reflected in my account by 05-06 Nov 2020, but I have not yet received the refund.
Please look into the matter and help me in processing my refund at the earliest.

Thanks
Munmun
