Complaint against SAFAIR and personel

I had to travel to Jhb on 14/05/2015 very early. The only 05:30 flight available was with Safair. Flight was booked on Travelstart. On arrival at the Safair checkin desk the lady on duty told me that I haven't paid for my luggage. I was stunt as this was the first time ever that I had to pay to put luggage on an plane and nowhere on the Travelstart docs it was stated thatI had to pay separate for luggage. The lady explained to me that if I booked our tickets on the website the luggage will be R150 per bag and if we booked at the airport it will be R250 per bag. On arrivel at the Safair counter the receptionist told me that I need to pay R250 as I did not made the payment for the luggage on the internet when booking the tickets. At that stage there were about 5 other people with the same problem. The lady at reception then said I can only pay R150 per bag but she just need to get the supervisor. The supervisor was the most unfriendly, arrogant, rude person I've met. She laugh in my face and told me that I will pay the R250 per bag or will not get on to the plane and she don't care if the system is not correct or someone else mad mistakes.
