Never again,the worst service ever

Pathetic service. I booked a ticket Wednesday the 26/08 for the 29/08 arranged for a wheel chair assist. Everything was arranged, I even called the airline the on the morning of the 29/08 asked if I needed to do an online check in, I was told no everything will be arranged at the airport. I discharged my mother from hospital, she needed to be admitted in a Durban hospital the very same day, I got to the airport - 55 min before the flight could leave (17:10). I was told that boarding is closed as per the notice boards the plane was still boarding, the lady at the counter says it to much of paper work to be done for a person in a wheel chair and we won't make it. As per my ticket I needed to be there 40minin advance, I was there before that, I pleaded for about 15min spoke to the supervisors at which time the plane is still boarding and the refused because there were to lazy to get someone to assist her onto the plane, My mother sat in a wheel chair and was in so much of pain &amp
