I've never received such pathetic service in my whole life

My ticket had been booked and checked in online, but when I got to the airport went to the counters with my bag to see whether they'll check them in or not as I've had instances where I take my case with. The lady told me I need to check my bag in, so I asked her, what is the criteria for checking the bag in because I feel there is no consistency as I'm always carrying the same case, so sometimes I'm required to pay for it sometimes I'm not. She tells me oh well then go ahead. At the gate they tell me I need to go back to the lady that was helping because this bag needs to be paid for, but if I was instructed by her I should bring the lady to them to explain. When going back I don't find her but a lady by Mreese Moomlall (I went to the extent of finding out what her name was as I was shocked at how she was speaking to me). She was exceptionally rude to me and she swore at me. All in all I missed my fight as I was told that they are no longer taking in luggages. The next flight was fully booked. So had to book the next one which was delayed as well. I'm so disappointed at the lack of customer service skills Flysafair frontline staff has.
