Intercape gives wrong location

My mother and het sister went to Worcester (De Doorns) on the Intercape. When they had to go back home, they bought their tickets, and when they had to get the bus, it didn't stop at the location indicated on the ticket. Because of that, my mother and aunt had to pay for a night in a guest house, that cost them R800, money they didn't really have extra. The tickets were exchanged, but the problem is, my mother wants the unneccessary expence of the guest house paid back to her by Intercape. They just told her that she didn't say she was going to stay in a guest house for that night, so they can't give her money back. Did they expect her to sleep at the pickup point? She just want the money back that she had to spend on the guest house because of Intercape's mistake. If the location on the ticket was right, this would not have happened. The new location is not updated yet, and that is why my mother and aunt missed the bus in the first place. I would appreciate it if someone can please assist us on this matter as soon as possible. Thank you and Regards Cindy
