Rude unhelpful staff strand us in Jhb international with our infant

So dissapointed in complete lack of interest in helping us.

We flew from Amsterdam to JHB, and needed to catch a connecting flight to Durban. On arrival, the Kulula online check-in website would not work. There were delays with our baggage, and so we arrived 2 min late for check-in. They were literally still helping a lady with check in but said I was too late and could not be assisted. I explained that we had been in the building, attempted online checkin but the website wasn't working and baggage delays were out of our control. The Kulula flight to Durban that we were TWO minutes late for check in was TWENTY FIVE minutes delayed, but the Kulula staff refused to try and help us. They were rude and unhelpful, utterly lacking in empathy, resulting in us missing our flight and being stranded with our 3 month old infant at JHB International Airport at 22:00 at night, with nowhere to go, even though the Kulula flight was delayed by TWENTY FIVE minutes, and we were on the premises and their own website wasn't showing online check-in!
