Huge DELAY for two consecutive flights? Terrible

First, I spent R32000+ and bought my father in law a business class, expecting the airline to look after my father. Check-in was terrible, with people cutting in lines by premium check-in? Everyone looked dreadful working there. My father boarded the plane, it was flying from JHB to HongKong, then HK to Shanghai, next thing the plane flew to Durban for a couple of hours?? Then it flew to HongKong, and he obviously missed his next flight! He got to Shanghai at 10pm. I had made arrangements for him already, everything was cancelled! I had a driver that waited for him for hours! This was 22nd Dec 2015 with flight SA 286. <br> <br> Bought my brother SAA economy from JHB to China (Expecting it to have better service this time?) , the check-in experience was absolutely terrible, WAY worse than business class and any other airline! The lady by counter was extremely RUDE. Nevertheless, he boarded the plane, flight SA 286 on the 6th Jan 2016. The plane AGAIN flew to Durban for few hours??? With NO food or any explanation offered? Luckily my brother didn't miss his next flight! My parents are flying 15th Jan also with SAA Business, I'm telling to change as it seem like a constant thing.
