Worst travel experience of my life

On 14 June I was on flight MN109. We were scheduled to depart at 7:50 pm. In the morning, I received an email stating that the flight was delayed two hours. I stay in Nelspruit and already had a 4 hour travel to get to OR Thambo. Ok at 9:25, we finally lined up to board. Nothing happened for another hour and we ended up boarding three hours late at 10:30. At this point we are already frustrated and angry. We fly for about an hour and 15 minutes when the pilot announces Cape Town has fog and two previous planes had to turn around but we will see. Ok another twenty minutes pass and they announce we are turning around. Everyone on the flight starts to panic. We hear that we will be provided with accommodation and the ground staff will be happy to help us rebook the flight. We can also have a refund if we want. We land again and wait an entire hour for the luggage to come out. My luggage as well as my sister's was broken into and gone through. (Nothing except food was taken which is petty but ok). Then we get upstairs. The line is three hours long. We started in line at 1:30 am. When we finally get to the front at 4 am we are told to come back at 7 am. All this time your staff is incredibly rude and unapologetic. No one has the common decency to tell us what is going on. When asked about accommodation we are told "Let me be very clear accommodation is NEVER provided." It is 4 in the morning and my home is in Nelspruit. Where am I supposed to go?? Ok we sleep on the cold airport floor, still not hearing any communication all the while your rude staff is telling us to go home and come back at 7 am so they can sleep. No apologies. No explanations. When 7 am comes we still have not heard anything and your staff is still rude and still has not apologized. Finally a guy comes at 8 am and tells us he can only get us on the 11 am flight (not the earliest one, no we get to wait even longer). We finally line up to go board for the 11 am flight; no the crew isn't here. We wait another half an hour for the crew. Again NO APOLOGIES. They show up finally after 40 minutes and also, surprise, don't apologize. I booked and paid more to have a seat at the front of the plane and on the re-booking I got a middle seat near the back. Ok we finally get to Cape Town. On the flight back, I was very rudely told by your check in staff that I need my marriage certificate to fly as I don't have a changed name on my ID. Previously I had shown it on my phone and that was fine. No I have to go downstairs to print it right now. Ok I go downstairs, print it in color only to come back and hear that she'd already checked me in and it was not needed. She was extremely rude and unprofessional and I unfortunately could not get her name as she would not tell me. After getting home, they told me I get a R300 voucher for my troubles. I have never ever in my life had service this bad and people be this rude to me when you were in the wrong. I don't know how you expect to be a company with paying customers because honestly it was the worst travel experience of my life. How does your staff just not communicate with each other about anything?
