My Flight has been cancelled by Airline. I have contacted Air Asia customer care and asked for full refund and it has been approved.
However in your site you are charging MMT convenience charges, for the airline cancelled flight, why should I have to pay the MMT charges? Airline has cancelled it and you have to get it from Airline instead of the customer.

for my 3 tickets I am loosing more than 1000 rupees
