Ibibo Group / Goibibo — Refund discrepancy with flights cancelled by the airlines

I have made the payment of Rs 48896/- and have got the refund of Rs. 29205/-.
Why airline has charged the cancellation fee of Rs.14034/-?
The flight was cancelled by the airline. As per the DGCA, the flights cancelled during lockdown will be refunded in full amount.

I have contacted Air India support I see that there is a major discrepancy in the amount refunded.
There two passengers in this ticket, They had provided the amount for each passenger they have provided.
It is Rs: 23, 499 INR for each passenger i.e total of 47000 INR .
They haven't charged money in the name of Airline cancellation fee as mentioned by Goibibo in Refund breakup INR 14, 034.

Please look into this. They had mentioned in the call they said It was cancellation from the Airline not from the Passenger nor myself.

I have raised a complaint and grievance both doesn't seem to be going forward
