Worse bus ride ever, will never take InterCape again.

Worse bus ride ever. The bus I booked was supposed to depart at 18:00 from Park Station Johannesburg to Cape Town,however we left past 7. The bus drivers were rude and were not willing to listen to our grievances bus number 137. The sleepliner was not value for money, no luxurious as promised. The bus ride took almost 20 hours.
