UNACCEPTABLE!!!

I was utterly shocked to be charged an amount that matches a third of my airline ticket to correct a minor spelling error on my ticket. By minor I mean removing one letter from my name. Mango customer service put me on hold for almost half an hour, I imagine in the hope to frustrate me. In contrast, very interesting that when I call to book or make changes to my ticket the phones are answered immediately. I was told that if I had called instead of making the changes online I would not have been charged, they proceeded to tell me that there was nothing they could do. I WILL NOT PAY R220 FOR REMOVING ONE LETTER FROM MY AIRLINE TICKET. I'm taking this further to the ombudsman.
