Safair mess

I booked two flights one from George to Or Tambo then from OR Tambo to Nelspruit, making sure that I had enough time to connect to the flight to Nelspruit. A few weeks before we were due to leave they cancelled the George to OR Tambo flight which meant we had to book the next day and at great expense (for us R2700) a hotel at the airport. We are retired and finding things extremely expensive saved for this holiday for more than two years then this happened? Their excuse is that they only guarantee from one point to another. Completely unacceptable.
