Poor services and arrogent Kenya Airways, avoid!!!

I have to changed my return flight from Mauritius. I made the date changing on their official website kenya-airways.com, and successfully paid USD76 panelty, but shows a teachnical problem and ask me to contact their agent. I called the contact numbers on their website, non of them are working. My friend told me their ticketing number in Jo'burg which I did called, but I had been told that they are just service Joburg airport customers, I need to call their Joburg office number or call centre number in Nairobi. I went to Cape Town airport counter, I have been told the same thing but all the numbers that they gave to me are not working. I have to call their Nairobi call centre, after few international calls and paid another USD150 this morning at 8:45am, I have been told that the payment is done, asked to wait for the new ticket. But until 11:30pm, there is no ticket has been issued. I have to call their call centre again, then been told the I have to wait for 10 mins more for them to issue the ticket. An airline so arrogent and poor services, even don't have a local call centre or ticketing office in the city where their are servicing, I have to spend more them R400 on international call fees but still not get things done!!! Please avoid this airline if you want to live longer!!!
