How to contact Fastway other than speaking with an unintelligent Intelligence

I am trying to get hold of Fastway to rearrange delivery to Hopefield . The only way is communication via the AI Bot who only knows 3 questions & is not showing any intelligence whatsoever. There is also no driver listed under Cape Town area. The contact number I have from a driver with previous delivery seems to not exist anymore as he doesn't answer my whatsapps. Is communication via email or whatsapp at all possible? If so, please advise.
