Baggage left stranded due to 2.5 mins and horrific service

Flight MN501 to Durban. I was literally 2 and a half minutes late to check my luggage in. No one wanted to assist. I am travelling on business with suits etc.. i get told by the manager JJ Louise at Lanseria " oh well you should have been a few minutes earlier". No client centric response. Just get blown off and treated like trash by your staff. Then the flight takes off 5 minutes late? Then i call your call centre to lay a complaint and get told i cannot talk to anyone i must talk to an EMAIL??? I mean in this day and age we communicate with human beings. So much for Customer Service - whats the use. Now i must go purchase clothing etc until the 7th April when i return on the useless Kulula Comair flight. I demand that i get a refund and also Kulula to pay for my bills for clothing etc that i now need to buy for this trip... To be told i am 3 mins kate and then your flight takes off 5 mins late and to get treated and embarrased in front of other people in the queue is not on. Kulula flights are always fashionablly late but we dont get to ask for refunds etc... but you get me to leave my luggage behind and not even offer an alternative... I want someone to call me!!! My company makes use of your airline and you make a lot of money out of me. But i will never set foot on your pathetic airline with the most miserable and rude employees ever again!!!
