Cleartrip — refund for cancellation of ticket

I cancelled a ticket on the cleartrip website due to personal reasons. I have cancelled the ticket within 5 mins. I should be eligible for a full refund but they have tricked me saying that the airlines have cancelled my ticket.
Please refund my full amount of 7882 as i need to book my next ticket.

The agents say nothing can be done. When i have cancelled the ticket through cleartrip, i request you to completely refund my amount that has already been paid.
