Airline not fair or empathetic

11 people were supposed to boad flight from DBN to JHB. We were here on time but due to long queues couldn't obtain the boarding pass on time. The self service kiosk was offline. 2 passengers after obtaining boarding passes were stopped at gate, even after they were seen running. Referred to service desk where consultants were rude & abrasive with us. It was still 20 min before time and whilst we pleaded to allow us the flight controller Fatima refused. We were on time yet due to poor service we couldn't get our pass. Instead of arguing with us they could have let us in. 2 brothers running to gate missed their brothers wedding.we need to get to work and drive further. This Fatima is most unhelpful , arrogant & uninterested in clients. She doesn't know what client service is about. This airline doesn't make concessions for its clients. There's no humanity shown. 1-2 people missing a flight is ok. 11 people is something else. It's a lesson well learned, never to use this airline again. Service attitude of staff is deplorable.
