Extremely Disappointed with SAA Australia – Unfair Charges

I recently flew with SAA - To and from Australia Perth and had a very disappointing experience. One of my suitcases was overweight by just 3kg. Instead of charging me for the excess weight, I was charged a full 200 AUD (approximately R2,450). I weighed my suitcase at home and it was exactly 23kg, well within the allowance. I believe the scale at the airport was inaccurate. Despite raising my concerns, the staff refused to assist and insisted on the excessive charge, billing me for the entire 26kg instead of just the 3kg extra. This is unacceptable customer service and extremely poor handling of a simple issue. I expect better fairness and professionalism from a major airline like SAA.
