Bad, Bad Customer service

I do bookings on a regular basis for a staff compliment of more than 350 individuals. Today one of my colleagues missed his flight When he got to the airport I asked him to put me on the phone with the consultant so that I could provide her with the payment details to place him on another flight. The consultant at OR Tambo airport named Jean was exceptionally rude, curt and hostile. Her attitude was appalling to say the least. She even went on to tell me that she did not have to speak to me or entertain my request. In all truth this is a new level of low and disrespect and disregard for customer service. Not only did she blatantly refuse to assist but hung up on me???
