Bad experience with FlySaFair

FlySaFair did me dirt, yesterday I was flying from Johannesburg to Cape Town, my flight tickets was from 09:35 am and I arrived at the airport by 08:30 and when to the check in Portals to check in my bag before boarding and one girl came to me and told me the check in for my flight has already been closed I should go to the boarding gates they will assist me which I did exactly as she instructed then I joined the line until a lady by the boarding gates asked to see my ticket and she said my flight is about to leave I should rush and get searched and pass to go and catch my flight which I did exactly that but when I am about to get search a lady told me that they can't help me because my bag is big I have to go back and check in my bag mind you it's a carbin bag but because they wanted me to miss my flight so I can pay more funds again I then went back to the information desk and explain what happened and the lady referred me to the FlySafair office so I can get help, I arrived at the airport at 08:30 joined the check in que where I was told that I should leave the line and go to the boarding gate, mind you they say that the check in closes 40 minutes before the we starts boarding, before they boarding gates closes I was already at the gate waiting for the security to search me so I can pass which they didn't claiming that my bag was big ,I then went to the office only to find out that I need to pay more money for the new ticket which I don't understand why because I did make time but their staff told me to leave the check in and head straight to the boarding gates ohh not to forget the manager whom was so rude and didn't even try to fix my issue but only focused on her phone and making calls, I then borrowed money just to pay the R752 that was requested and I went straight to the very same line that I was told to leave to check in my bag only to find out that I have to pay for my bag again another cost on top of what I fought for because I had not another cash to pop out, what ****ed me of is that why didn't they tell me about all the money that i have to at once ? I borrowed again another money so i can check in my bag and leave because i was now worried about the time as i was going to work, in Total i paid R2900 just for flying from Johannesburg to Cape Town which i had to borrow from people and now i have to repay it with interest.FlySafair service is bad and if that's how they make more money that not cool at all,the workers are rude most especially the manager Beverly. I am disappointed
