Mango does not inform of delayed flight

On Thursday the 24th March 2016. I had booked a flight so that I could attend an event in Durban for which I was a speaker. On the Thursday, I had to take two hours leave to get to the airport in time to make my flight. When I get to the airport at 15H30 I find out that my flight was delayed from 17H20 to 18H35. I had call my transport services to make new arrangements due to the delay and had to ask to be moved to the last speaker. While waiting at the airport from 15H30 until 18H35, eagerly waiting to leave. Mango flight JE352 had still not started boarding. I eventually left Cape Town at 19H10 after expecting to reach Durban at 19H20. When I reached Durban, my luggage took over 20 minutes to come out and was damaged. Worst trip ever, I didn't get to speak at the event as I pitched up late and had no transport after arriving late at Durban King Shaka Airport. The next day, mango sends me an sms after the incident, would have been more useful if they had sent it to me before the flight, I wouldn't have lost 2 hours of work and I would have been able to make better arrangements in advance.
