Bounced off flight

I was booked to fly to Cape Town kulula HXPAYV at 15.25. Checked in online the night before, but unable to print ticket (seat allocated 30A)<br> Traffic delay to airport, but arrived before 2.55- machine refused to print my ticket, got to check in (hand luggage only) - staff at check in took a good 10 minutes to get through to gate controllers, but they eventually said they were given authority to issue my boarding pass- raced to flight, but was blocked by 4 extremely unhelpful ground staff (one called \Granny\")<br> I was blocked from boarding that flight- proceeded to pay partner British Airways R2400 to get onto next flight, in the interests of salvaging the trip.<br> Client liason is sticking to the idea that I was late for the flight, period. I wouldn't have missed it if the ground staff knew what they were doing ie. got proper authorisation from the gate controllers to print the ticket
