Cleartrip — Cannot get my refund

Dear Sir.
I had a original flight schedule to Delhi PNR number CFKNGY at 6:05 am which was re-scheduled. Based on the above I had made the booking for the next flight in the same day to return on the PNR number SPNQPN. Since the first flight we are not able to take so we have to cancel the other booking also because of the first flight reschedule.
You are kindly requested to cancel both our bookings and refund the amount back. I think I was able to do for the first flight from kolkata to Delhi. But not for Delhi to kolkata. Please cancel this one also without any deduction of charges.
Looking for your urgent kind response.
