Bad service Flysafair

20/05/2018, We were on our way back from Lanseria airport to Cape Town after a Karate tournament. We were a group of 9 people that needed to board. Our flight was 8.50. we checked in way before 8. we sat in the Wiesenhof Restaurant for a cup of coffee awaiting the flight. Myself and 2 other karatika went ahead and was at the boarding gate between 8:25 and 8:30 we were told that we are not allowed to board. On the plain tickets it clearly states that you need to be there 15 min prior to take off. I lodged a complaint with the airlines where I was told that 8:35 the gate was already closed. I explained that I was not with the group we went ahead not to be late. I was told that other people also complaint and they said 8:35, thus making it out that I was lying. I was in line to go home at 8.30 I was told no go. I had to pay another R581 to catch the next flight to Cape Town. As I am a single mom I had to hastily make arrangements for someone to look after my daughter until I arrived home. This was totally not acceptable. What is also unacceptable is the fact that we were told that our claim is being expedited but till date we had not further communication of any sorts. no matter how you try to get hold of sombody. Will I recommend this...... not sure. Although they had good servers on board the ground Personnel leaves a bad taste in your mouth
