Delayed Flight & Poor Service

On Friday, 3 April 2015, I left my elderly mum @ Lanseria Airport at 4:45rpm for her scheduled 6:30pm flight to Durban. Being a wheel chair passenger, we were asked to report to the airport much earlier than other passengers which we did. My mum called me at 7pm, saying that she had still not boarded and was told that there had been a delay in the flight. I was immediately concerned about her well-being as she is also diabetic and needs to eat regularly whilst taking medication. I called the airport and asked about the flight delay and also expressed my concerns about my mum. I indicated that if the flight was not leaving shortly, I was willing to pick her up and asked if they could let me know accordingly and then move my mum's flight to the following morning. I also asked if they could please check on my mum for me and give her refreshments and something to eat but they did not. During the course of that evening I received numerous calls from them indicating that I should pick up my mum and as I was on my way out, they would call back and then say the flight would be boarding in a few minutes .They only boarded at 8:45pm.This resulted in mum being very stressed and ill.
