Kulula Supervisor with BAD attitude and RUDE

We booked a flight from lanseria to Durban on the 25th at 9:25pm was the departure.We living in Rustenburg and it take approximately 1hr 20 min to get to the Airport and the traffic was hectic coming as well as a accident on the road and due to that we were 5 mins late and was there at 9.00pm to book in and when we arrived at the check in we were told that we cannot be helped and that we must go back home cause their books and figures were given in already, The supervisor of Kulula Airlines (Nomasonto) and (Mamelo) which did not have any name tags on them and We had to ask for their names at Kulula Front desk, We do understand that We were late but there was no need for these ladies to be so rude and did not understand my situation as we did not have a lift back to Rustenburg, furher more they were so loud and arrogant and was screaming out aloud at me, what happens to Exceptional customer services nowadays, she was so rude and arrogant she told the cashier who was rebooking the flights for the next day to rebook my 3 flight tickets and we then got frustrated and mentioned that MANGO AIRLINES gives the best customer services. The supervisor told me that we must not say things like.
