Bad services & bad attitude

I have never experienced such bad service and attitude from flysafair like this morning. I have always made use of them and today was my 1st bad encounter. I arrived at the airport ready to check in. 1st problem was that my bag was too big for handluggage and it was too late to book it in. Which i completely understand. Then i decided to fly without the bag, gates closes at 06:55. As i make my way through security, i arrived at the boarding gate, they told me sorry ma'm the busses has left. Ok then can't you make a plan for another bus to take me to the airplane. No sorry ma'm. With a don't care act and does not even show any effort to assist me. Now i have missed my flight, don't get any refund, no more available flights for the rest of the weekend and if i want to change the dates of my flight i must pay R1800. I am so angry and disappointed
