Was travelling to visit my sick sister in UK on Sat 7th (to be with her during treatment on Sunday morning) December and had booked Aircoach from Derry to Belfast International. This bus did not turn up. I phoned the number on the poster at the bus station but was only Mon to Fri for response. No email received and on reviewing on line forums there was no indication of the service being cancelled. I subsequently missed my flight. I then contacted Aircoach for response and no reason for no bus service was given. They apologized and reimbursed me the bus fare. I incurred the the cost of the flight and Aircoach were not prepared to compensate me for this cost incurred as a consequence of their failed service. Aircoarch prompted me to seek flight compensation from either the flight carrier or my insurance. Overall poor service, lack of communication and apathy to the situation.
