awful experience - never will i fly mango again

I am very disappointed with mango and their team, on 20/09/2018 flight JE628 13:35pm was delayed so many times and finally we departed at 17:36pm and only arrived at lanseria about 19:00pm- my family waited at lanseria all this time for me to arrive. On the 24/09/2018 my return flight JE627 11:50 am, I arrived at the airport 11:30 due to a road block on the N14 , got to the check in counter and I was told im 5 minutes late and I can not check in and if I didn't have a bag then they could have checked me in, was then sent to the customer service counter spoke to kopano Masango, i was then told I still can not get onto the flight without my bags after given the option I could by the check in counter. She charged me a admin fee of R374 after asking her if there is no cheaper option, I later called the call center and was told the cheaper option is to make changes online and it would be R280- she was unfriendly and wasn't even able to call her call center for me. We asked for the Supervisor Moore Dube, who also didn't assist. It would have taken me less than 5 mins to walk to the plane at 11:30 as the plane was only leaving at 11:50. I had to pay an additional R905 to change my ticket to the next flight which was at 17:25. Got to the airport and checked in , I spoke to the next shift supervisor and she said that they could have made a plan for me to board that flight as the ticket says the gate closes 15 mins before the flight. This was an awful experience for me - its ok for them to have the flights delayed and when I was 5 mins late they could not help me. i will never ever again fly mango and I will definitely not recommend mango airlines. I will be taking this further.
