Keith O.
My plane was late taking off from Toronto, so I didn't make the 9:30am bus as scheduled. When I asked about getting the next bus without losing my money he told me that theres no returns and to take it up with head office. Very disappointed in this national ambassadors attitude and I payed for a taxi to milton Keynes because I had a long flight and iwas very upset.
