1)I booked my tickets from xxx to xxx and back but due to some personal emergency, I had to cancel my flight. Amount of tickets was Rs 48000 but I received only Rs 16000.
2)Cancellation charges are Rs 2500 per passenger per side but I was charged 3500 per passenger per side.

3)Please refund back the amount of Rs 8000 as there were 4 passengers.

4)I have called Airlines a number of times but no good.They have to deduct non applicable extra amount even in case of personal emergency.
