TAAG Airlines poor service

Was booked for a flight from Lagos to Johannesburg on the 3rd December. Flight was schedule to leave 3rd Decemeber @01H25 , and was suppose to touch down is South Africa @ 14H40. We set at the Airport in Lagos till after 05H00, and we were only given an update as we complained, and we were promised that we will be right on time in Luanda for the connecting flights to Joburg and Cape Town. We arrived in Luanda, and we were told to wait. We started boarding the Flight at 10H20, that is the time of Departure. That was not much of a problem, but to be made to wait on board up until about 13H20 with the doors not closed, only to see one gentlemen come in then and doors are closed. So the flight delayed over 70 passengers to accommodate only 1 person that was late, and no communication or whatsoever with the clients that have paid for the services. This is another level of disrespect, and inconvenience. With that the flight only arrived in OR Tambo exactly about 16H05 (South African Time) and I missed my flight from Joburg to Durban. TAAG Airlines was not even interested in assisting me after they inconvenienced me and told me to find / make other arrangements to get to Durban as I did not book the Joburg - Durban flight through them.

So this has me wondering if is this how their business is run? Disrupting and not respecting their clients time.

I sent them a complaint and they responded with a *** and promised that someone will get back to me. Up to today, I haven't received any update from them.
