Arrogant staff

Bad experience at the Cape Town international airport with Flysafair junior and senior staff members. Just when I was about to check my luggage they told me it’s over 7kg and that the boarding gates are closed coz I did not pay for the bag. My issue here is how come at Lanseria Int airport they weighed my bag and they never made me pay. I missed my flight at Cape Town int for the luggage drama The gentleman did not even bother to take it up with the office or Lanseria for that matter since there’s inconsistence and inconsistency between the two airport and I am not gonna allow flysafair staff to tell me how the two airports operate I am a customer it’s not my business if Lanseria policy differs from Cape Town I expect both airports to apply same rule as it’s same company.
