Pathetic Service/Worst Airline ever

On Friday 8/12/2017 I was on the airport since 12;00. My SA Express flight 1340 was scheduled and booked for departure at 13:35 from Durban to Port Elizabeth. Prior to boarding there was a slight delay, however we all were boarded and entered the bus which would drive us to the aeroplane, however a short while later we were told that we needed to leave the bus and return to our seats due to a technical problem identified on the aeroplane. The engineers were looking at the problem and feedback will be provided as soon they can. Anyway the flight was delayed for an hour, the information board then changed to another hour later and then later it reflected 17:40. and then finally 21:40 After we were informed about the initial technical problem, the saexpress employee left. No saexpress employees was available to give us an update as to what was going on. We just noted changes on the information board, then we noted our flight was cancelled. A new flight 1348 reflected, nobody knew what was going on and the 13:48 flight was additional people thats flights was delayed and eventually cancelled. SaExpress employees were missing. All customers were upset since we were not aware. We all eventually approached another desk where an SAA employee was present and demanded to see management. Later the SAExpress employee arrived. Informed us that unfortunately both flights were delayed and plans was made for a bigger plane to accomodate everybody. most of the questions the team leader could not answer. We then requested someone that can provide feedback. Everybody was really upset. We were issued with a R75.00 food voucher for our inconvenience and saexpress employees/management were not very helpful. We eventually boarded the new flight arranged 10 hours later and arrived in Port Elizabeth close to midnight. On arrival most passengers were informed that their luggage was left behind in Durban because the saexpress employees did not load it onto the new flight. This made us even more upset as passengers. the service is disgusting, the saexpress employees/team leaders were not helpful or did not look empathetic to our concerns. We were just told to contact their Customercare help desk to lodge complaints. Our luggage only arrived the next day. I needed to collect my vehicle the Friday before 5pm and was not able to do so. I have called their customercare line on 3 occassions today, and there is no answer. I have used the customer care contact details listed on their website, but no luck.
