Vodacom pretends there are ways to contact some sort of customer service other than phone.

I have been trying to contact Vodacom customer support for weeks now. Their customer care email still gives auto-responses saying that there is no longer a working customer care email address and says to use the online chat. Unfortunately the only route the online chat offers is either to phone Vodacom or use the customer care email address. I was told by Vodacom that someone would contact me, but I have not yet received any emails from Vodacom regarding the problem. So Vodacom now provides no working route to contact them except phoning. Why are there claims of routes of contact that clearly don't work and which Vodacom clearly has no intention of making available?
