Translux/city to city

I bought a return ticket on Monday 4 April 2022 online with computicket for friday 8 April to Louis Trichardt. On Wednesday I received a call, informing me that the bus I'm supposed to take back the following Thursday, has been cancelled, and I have to go to translux office for a full refund. Needless to say how disappointed I was for translux cancelling my holiday. Now we have endless problems getting my money back. Arriving at the translux office, they say they know nothing about my refund, and they know nothing about any cancelled trip. Just goes to show why they have such a low rating.
