Translux/city to city terrible service!!!!

I have made a bus booking through computicket for a translux bus 2 weeks before my departure date. My plans have changed and I needed to travel a day earlier. I wanted to amend my booking and pay whatever extra since it's 48hours in advance. I called translux office and the lady said I have to change it at the ticket office in park station which is 40km that I have to drive, if that's the case I would have drove there to make the bus booking instead of doing it online. I tried more than 10times to call translux office in park Station and there's no answer. I cannot amend the booking online because there's no option to do so. I sent an email and the email address doesn't work. I tried calling city to city/translux offices in Pretoria, they are incapable of answering their phones as well. This is absolutely ridiculous and to think they need the business due to covid but are not willing to put in the work for it. That's the last time I will deal with translux/city to city.
