Alliance Air — Flight canceled by Airline and refund declined

I have booked a ticket with them, Flight was canceled due to a technical issue and I was informed that a full refund will be granted hence I took another flight. however, they deducted more than 95% of the ticket charges in the name of cancelation charges. customer care is pathetic, airline's service is even worse. they did not give refreshments even after 6 hour delay plus accommodation was declined and now even the refund is declined.
