Atrocious service

My daughter studies in India - so she travels back home between 2-3 times a year. And I visit at least twice a year. But going forward I will NEVER travel on SAA ever again. It is not the fault of the passenger that SAA no longer flies directly from Mumbai - it has taken me over two months to try and make a change to her booking - with absolutely no success. Now that the time is nearing for her to fly back - it will cost me double the original airfare for her to fly one way. How can this be justified. I know that I am not going to get a response from SAA, but this is my way of getting rid of some frustration. I have been phoning their call centre and reservations on a daily bases to make the change....and every time you get a different person and you have to repeat your story and still NOTHING gets done.
