Special assistance

After 45 years of marriage my mom lost her husband and during this very difficult time she received the worst service from flysafair. When we arrived at the airport my sister went to their check-in desk to collect a wheelchair from my mom as she is on crutches. They then told her that there is no one to assist and that there is no available wheelchairs and that my mom should slowly move towards their check-in area and wait for a wheelchair. My sister then went to their help desk to complain, where she saw a number of wheelchairs. She was then told that she can take a wheelchair and push my mom through herself. All this after we clearly indicated, when booking her ticket, that she would require special assistance.
