Very Bad Service

I am utterly disgusted in the service I received from Flysafair! I was scheduled to check in on 07/05/2015 at 18:15 (JHB). We travelled from a nearby town and there was an accident just before the airport, needless to say the traffic was backed up. When we finally got to into the airport at 18:05, we rushed to the nearest check in kiosk where too young gentleman helped us. They had no clue as to what they were doing because clearly they were struggling to get us checked in. They then said we should rather go to the counter which we did and stood in a queue for a few minutes. We were then told it was too late to check in. They then referred us to the ticket counter where Ayesha told us there's nothing that can be done. I asked to speak to the manager, to which she rep****, she WAS the manager (no name tag or identification). She refused to help us even though I explained the situation to her and it was myself my wife and two kids (2 and a half and 4). I was also scheduled for an important meeting the next morning! This meant we had to get a lift back to the nearby town and back the next morning only to be on stand-by. Is this really what Flysafair thinks of their customers?!
