Will never use Greyhound bus service again

Made a booking for my daughter in December 2024 from Johannesburg. Translux bus from destination had tyre trouble and arrived late at bus terminal resulting in my child missing the bus from Johannesburg. Greyhound office staff very unhelpful with stranded child to get on forwarding bus even after I phoned the ticket office myself and explaining that late bus was no fault of passengers. I was told no refund of ticket to purchase new ticket, even though situation was out of passengers' control of other bus being late. Where do they think people must just scratch out more money for a new ticket?
