Baddest experience ever with an airline

So we went down to Durban to fly my oldest back from his hockey tour because unlike his mates he take his academy very serious and he needed to get back to study for tests. So we didn't want to put him on an 7 hour bus ride. Our bad experience started early morning 22/4/2019, when our 10:45 JE258 was delayed to 12:20. 1 1/2 hours later. So we said ok fine, we'll book in and wait in the Slow lounge because we have 3 boys. Which now cost us money which we didn't budget on. So we went to the Mango book in counter, with his hockey stick (we did fly with Kulula last time with hockey sticks and they told us very friendly at the counter because it is 6 sticks we need to wrap it and then they will book it into fragile. Mango was not that friendly at all. I asked them about the stick and they said they will put it in fragile. I told them it is very expensive, won't it get lost. Then the girl said no, take my boy's R3 500 stick and put a sticker onto it, when my husband flip they had the baddest attitude. When he then go to rather wrap the stick they told me that we should have told them that it was expensive because they don't know a hockey stick. Seriously, I told them it was expensive when I asked them not to lost it. And then they told me it is considered a weapon. So surely if they know that it is considered a weapon they will know to told us to rather wrap it and then put stickers on it. Their attitude towards myself was also soooo bad. Just for that I thought never Mango again. So then we went to the Slow Lounge, and again we received an sms that the flight was delayed again, and again. Then my husband went down to see how far are the check-in process, because by now my oldest was fast asleep on the couch. He came back saying the flight was delayed again, no sms, no explanation. So eventually we got onto the plane, with not so happy Mango staff because they were about to take a break. My middle boy got sick on the plane because by now the weather was very bad (which it was not at 11:00). So he was feeling sick and grumpy. We landed about 15:05, more than 3 hours after our planned time, and waited a long time for our baggage. Then we waited about 30 minutes for our Valet Service because all of a sudden they had to bring our car much later which clashed with other flights. We should have been in JHB by 11:50 and then would have been home by 12:45. We got home 16:30, 4 hours later than planned. My boy could have just take the bus, and we would have saved a lot of money. Your service from start to finish was not nice at all. Our whole day's planning was gone and I only went to bed after 12 because my oldest school Jacket and hockey clothes had to be washed for school the next day. The baddest experience every and like everything in life it just snowballed because Mango couldn't keep their flight time. 1/2 hour should have been fine but your staff's attitude and 3 hours later was not funny at all.
