Ibibo Group / Goibibo — convenience charges need to be refunded for covid cancellations

Address:

2nd Floor Tower A D, Bhaskaran Rd, Kensington Gardens, Kalhalli, Halasuru, Bengaluru, Karnataka 560008

I have booked flight ticket with spicejet airlines via goibibo group pvt. Ltd. (The agency). Spicejet has created a credit shell (Voucher) for the amount they received from the agency as the flight was cancelled due to the ongoing covid.
Goibibo group pvt. Ltd. Has made the credit shell of the same amount that spicejet has created and the convenience charges charged during initial flight booking are not added in the credit shell amount. Another point is that they have made a policy to charge extra money (Re. 1) from the passengers if we book another flight ticket with the same airlines (Spicejet) via their web portal and the total booking amount is of the same or different amount that of the credit shell amount.
I demand that goibibo should refund the service charges to me they charged for the booking as the above mentioned conditions are against customers' right. This is not customers' fault that they are charging extra money or withholding convenience charges.
