SAFAIR call centre offers poor service

I tried to book a flight online in January from ORT to Cape town and back 14 / 18 January. I entered my credit card details (as I have done many times before) and submitted for payment. I got an error message \Internal server error 500".<br> I called the call centre for assistance and the agent found my booking but said the payment had not gone through. She said there is no facility to pay online again as Mango has this option and asked for my credit card details. I told her she must be mad I am not giving my details over the phone and she cut me off - extremely great customer service. I called back again and another agent could also find my booking created and told me he could process the payment if I gave him my credit card details.....I told him too that it is not acceptable to do this over the phone as it was not secure and asked to speak to someone in management. He said nothing put me on hold and after listening to electronic tunes for longer than 5 minutes I cut the call. """
