Debit order change

I tried phoning the Vodacom help line to get assistance with changing my debit order date. After completing what seems like 100 options, I finally got to the chat bot, only to be directed to try via the website. So then I tried the website and after a very ling search regarding debit ordera it tells me to call the help line/customer care number. I am fed up! Please help and assist your Clients Vodacom !! I am a new customer and already I am regretting making this move.
