Poor and Pathetic service from Kulula

We made a booking for 3 November at 12h50 from JHB to CPT. Kulula changed our booking without consulting us to 8h50. We stay ±3 hours away from JHB. We are two women travelling to JHB. We cannot travel at night as it is very dangerous on our roads. I have been contacting the Kulula call centre multiple times. After ±20 min every time on the phone, there was no answer. I have tried to submit a complaint on the Kulula website, but that does not work. I receive a 'run time error' every time.

We have to be accommodated to times which is best for US! We are paying for the tickets and Kulula is delivering a service. This is very poor service delivery from Kulula. Where else can we complain about this poor and pathetic service from Kulula?
