Abhorrent customer service by SAA

When flying from Hanoi Noi Bai on KA 294 to Hong Kong airport on the 9/8/2015 our flight was delayed by approximately 30 minutes. We were still on time to board for our connecting flight to South Africa on SA 287. We were very rudely pulled out of the boarding queue by your staff with no explanation. When we demanded an explanation from your staff we were told that because our flight had arrived less than 90 minutes before departure SAA was unable to guarantee our baggage would be on the flight and therefore were unprepared to forward it later at their expense. We explained that I had a connecting flight to Cape Town and that both being doctors, we were expected to be at our respective hospital the following day. We were treated extremely rudely by SAA staff and affiliate staff of your airline at HK airport. We were never offered food or accommodation vouchers and not a single person apologized for the massive inconvenience of flying for over 26 hours, via three different connecting flights with additional lay overs. Furthermore we have still not received our baggage and are unable to locate it. This incident is completely unacceptable and I will never use your airline again
