Cheapticket.in / Airtickets India — tickets refund amount more than entire ticket itself

I booked flight tickets from bangalore to delhi. They costed me inr 3, 300 each. Now, i want to reschedule. According to them, the rescheduling penalty is inr 3, 900. Which is more than the cost of ticket itself. Which means i will have to pay to cancel my tickets.

In that case, i just wouldn't show up for the flight and the seat would remain empty which is a worse situation for everyone including the airline.
I don't get why they do this. Who would ever pay extra for cancellation?

I wish to have a better refund value for my tickets as i'm cancelling well before the schedule.
