bad service - no service

My family and I boarded a flight on Saturday 1 January 2022 to OR Tambo scheduled to take off at 6am. We never checked in our luggage and assumed that all was ok to board the plane with the suitcases we regularly use. The fight was delayed by an hour due to passenger luggage issues etc. Needless to say, everything booked ran 1 hour late. That was ok - we dealt with it although our 3 children, up since 3am were extremely crabby at this time. Fast forward , a week later - Saturday 8th January 2022. Flight MN 191 was scheduled to leave at 5pm and we made it to the boarding gates at around 4:30pm - same luggage as we had when we flew the week prior, only this time to be ARROGANTLY told by LEBO (I think here name was - but please do check your records as she has her name needs to be mentioned - I was way to angry to take ANY DETAILS AT THE TIME) she cannot allow us on the aircraft because our 2 of 4 bags were too big! We went back and forth about the fact that we weren't stopped in CPT when we flew to JHB and if it were a problem we would gladly have sorted it out, but we needed to make that flight. She completely dismissed us or our plea to speak to the supervisor for assistance, all she kept saying - very RUDELY- was you cant get onto this flight - these bags need to be checked in! We tried explaining to her that it was 4:40 and that we would never be able to make it and that we would glady sort it out in CPT or would like to speak someone who could help. At this point our kids were crying because of the commotion and yet again extremely crabby because of a 4 hour drive before coming to the airport. She then told us we have 15 minutes to run back and get our bags checked in before the plane departs. I decided to stay at the boarding gates with my 3 children as it was quite a distance to the check in counter - we explained this to her! Not even 5 minutes later, after she TOLD us to get the bags checked in, she POLITLEY closes the boarding gates with absolutely no explanation, further assistance or any kind of customer service WHATSOEVER. My husband then calls and tells me its too late, THERES NOTHING LEFT TO DO????????? WHAT!!!!! ARE YOU EVEN KIDDING????? SHE TOLD US TO CHECK THE BAGS IN (thinking that maybe the flight would yet again be delayed slightly as it was when we initially came to JHB). We were then forced to sort out the issue and after paying R2400 later we were put onto the next flight????? Money that we needed to BORROW to get home! ABSOLUTELY RIDICULOUS!!! This woman and her assistant MAVELA MONA have to be noted as the worst customer representatives TO DATE!!! They are RUDE and lack any kind of human empathy. They spoke to each other in their own language, refused to let us speak to their supervisor and blatantly ignored our pleas for help and assistance, instead FORCED us to the check in terminals knowing very well the boarding gates would close and we would no longer be their problem. I am utterly disturbed by their lack of service and disgusted by how they treat individuals and will never ever fly with or recommend Kalula airlines to any of my friends and/or family. I will, further to this, expose these representatives on every media platform I am fami**** with as these people have absolutely ZERO empathy for customers and NO respect for the brand which they represent!!!! I am expecting a call from a MANAGER to further explain this!!!
