DISGUSTING PRACTICES KULULA

I booked my son and his fiance from Durban to Johannesburg travelling on the 22nd December, returning on 2nd January. This was done on the 5th November. Due to a tiny error, I typed her name as Caralyn instead of Coralyn - one tiny letter difference. Surname correct, ID number correct. Kulula refuse to allow this one letter change and said that she will not be able to board the plane. I paid full fare with luggage. I even offered to pay an admin fee for the change - not a chance. How on earth can this be allowed? It is absolutely disgusting. So for the sake of ONE LETTER, I have now had to pay full fare for her again. This is a Christmas reunion and I am a pensioner. Plus I held on for 15 minutes on the one number - no answer, and then 15 minutes on the other number before I managed to speak to a human, if that is what he could be called.
