Hopeless service

I had the most irritating experience with FLYSAFAIR today. I had a flight booked and had to change the return date. I could not manage to do it on the website because it did not give me the options for the following day, even if I picked it on the Calander. Then I phoned them, and the answering service said the Q is 10Min, or I can leave my number. I left my number but after three hours I still did not get a call, so I called again. I stayed on the line for longer than a flight from Cape Town to Johannesburg will take but still no agent. I then tried the App, but it did at first not found my flights, then when it did it bombed out 9 times before I finally got the booking changed. I can just hope that the flight will be more enjoyable that their online services. It took me longer that 2 hours to get the flight changed, while a automated woman's voice on the phone keep telling me how easy it is to do it online. When I called the most useless organization in the country "Home affairs they answered in 45 minutes, I did not get an answer from Flysafair in 120 minutes.
