Bad customer service!!!

I Booked a bus from Mount Ayliff to Johannesburg for April 18, 2025. I spoke to an agent from customer service unfortunately she did not provide her name. I had called in to make some changes on my booking by changing the date to April 19, the lady said it’s possible and changed it. I requested that she provides a booking confirmation and refused and requested that I text on WhatsApp. I’ve literally been trying to get through to an agent for the past 35 min with no luck to get the booking confirmation, she even refused to provide the Ticket reference for that matter. I called in again and luckily I went through to her, I requested that she provides a booking confirmation and she said she’s been waiting for my WhatsApp text! I mean I’ve been trying to get through to an agent for the past 35 min with no luck, on top of that she hung up on me when I requested that she changes the booking to the original date of April 18, now I’m stranded in a Town, unable to get any assistance. The level incompetency and lack of customer support is sickening, the fact that she hung up while I was trying to get assistance is even worse. I mean how will I travel without any booking confirmation, let alone a reference for that matter? I’m disappointed honestly!!!!
