Disgusting. Ripping people off

My 85 year old mother booked a seat on Intercape from Midrand to Kuruman for Saturday the 22nd June 2019 at a cost of R314.00. When I asked the driver if my mother could sit down stairs in front he said the seats were fully booked. A Lady that was sitting in front offered up her seat for my mother. The driver was very rude & arrogant. He also nearly left a passenger behind. Yesterday I booked a seat for my mother to come back from Kuruman to Midrand this Saturday the 29th. ONE WEEK FROM THE 22ND TO THE 29TH THE PRICE HAD RISEN TO R1112,00. How the hell can the price rise by R798.00 in one week? I spoke to Samantha of Intercape today & she had a I don’t care attitude. As far as I know the front seats are reserved for the ELDERLY & DISABLED. She kept on saying to me that seats can’t be reserved & the price is what it is as it’s school holidays & peak time. IT WAS PEAK TIME ON THE 22ND AS WELL. So please tell me what’s the difference in the school holidays & peak time between the 22nd & the 29th!!
