e-Ticket number (***)

I just experienced the worst flight check in of my life!!!!!!!!

I booked a flight Flight - Mango (JE)- 148- 27, 2019 Confirmation number RSWTTL I tried to book online but I consistently got an error: " your booking reference number us invalid . Please verify your details. your booking reference number needs to match the date of birth of one of the passengers." e-Ticket number ( ********** 576222) When I came to the service desk by the airport they told me that I am too late. I need to book the next one. And I was there 30min before the flight departure time as I had to stand in line for over 15min for check-in. The lady referred me to another service desk where that lady was not even interested. She was very very very rude. But in any case i was informed to pay an extra 496 ZAR to book the next flight!!!!!

I find d this totally unacceptable, seeing that I would simply have booked in online and made my flight seeing that I wouldn't have to wait in the queue for manual check in.

Worst flight check in process ever!!!!!!!
