Very bad customer service

Booked a Bus ticket to Durban from Johannesburg Park Station, departure time was 22:00, the bus was delayed by 30 minutes and no communication was sent. No one at the terminals was able to advise, they communicated the delay only after calling the call center, when they advised that the bus will be there in about 15 minutes, and of course it was an estimate. To add the cherry on top, the charging points on the were not working.
