Service humiliation and no communication of Airline

I am To whom it may concern

I am a passenger booked with boarding pass seating confirmation received via email and Lufthansa App. I booked the above mentioned flight ticket with Flight Center dated 2024/04/16 paid for to the amount of ZAR 30 378.41. My departure date is 2024/04/26 at 17:45 from Cape Town International Airport LH577 to date 2024/04/27 at 05:30 at Frankfurt airport. Date 2024/04/27 at 10:25 from above airport LH 978 to Dublin Airport. I completed my checking in online that is how I received my boarding pass. On the date 2024/04/26 with excitement and packed with all adhered regulations and terms of baggage required and still very excited I decided to report at 14:15 at Cape Town International Airport for checking in at the counter but to my dismay and humiliation I was redirected to the documents counter I immediately contacted the flight center agency who insisted my documents is checked and correct. I felt so ashamed to stand there at the counter while individuals was talking to the flight center agent using my cellphone and airtime and no one can give me proper answer after all the trauma I was told I cannot bard the said flight I was denied boarding I just felt so sad humiliated and disgusted that I cannot board I worked so hard to save for the trip and I was just like that denied boarding with no proper explanation. The flight center eventually told me I have to go home she has contacted the airline and spoken to a Rep and I will get feedback on Monday 2024/04/29. It breaks my heart to know that a airline that I would fly with for the first time did this to me.
