Cleartrip — cancellation of flight tickets-receipt of negligible refund

My trip id : [protected] — i had booked my tickets on 20.03.2018. Rs.16740.00 was charged to my account. My ticket was a refundable ticket. I cancelled my tickets on 16.04.2018. I am surprised that on cancellation of this refundable ticket, you refunded only rs.2322.00 to me. How can you deduct such huge cancellation charge? That's not done.
I would request you to refund rs.16740.00 to me at the earliest, failing which i shall go to the appropriate forum to recover my dues.
Thanks and regards.
