Cemair worst service

First the ground staff when I arrived at the King Shaka international there was nobody at the counters I didn't have any bags to check in and only needed my boarding pass and I informed the staff at the ticket sales to assist they were more interested in playing with their cellphones,I had to get my colleague to send me the boarding pass via what's app as my laptop battery was low,then the plane was delayed,we waited when we finally boarded it was a small plane,it was very hot we requested the Aircon to be turned on and after 20 mins the head air hostess informed me that she has requested this from the captain but he stated that if he switches the Aircon on then this will slower the plane and we need to make up for lost time,the entire flight the Aircon was off even though it was very hot.The air hostess served us sandwiches without even a serviette I requested a serviette from her and she was rude and stared to me she does not have any on her and stated she will bring to me but she never brought serviettes,she seemed disinterested in giving us serviettes or assisting anyone.We landed at about 16:40 and we were meant to land at 16:00 no update or apology from the captain or crew.
