No assistance

I booked a flight with Fly SA fair on the 20th of September for the 7th of November from Jhb to Cape Town to go home. I had anticipated that by then I would have given birth and my baby would be old enough to fly as my due date was 25th October and was convinced my baby would come early. I only booked for myself as they needed a date of birth so I had told myself I would just need to add her to my booking when she arrives. As these things happen I ended up giving birth on the 5th of November and was only discharged from hospital on the 7th. I called the call centre and explained that I needed to make a change and was told it was too late to make the change as it was close to the boarding time when I called and I would need to go to the airport. I advised the lady I spoke to that I couldn't make it to the Airport as I just got home and recovering from my operation. She said in that case I could send an email and they would help. I sent the email but never recieved a response. I then tweeted the FlySA fair account to try and get help but still no joy. I'm very disappointed at the lack of service from FlySAfair especially because I have used them for the past 2 years and have never had issues but now this? I don't think that this matter was dealt with in the right way and I refuse to accept that my money went down the drain just like that.
