Vodacom the worst

Vodacom don’t know what customer service is. After been sent from pillar to post, and holding on from one to an other music tune , still no help. We change our Wiffi from Telcom to Vodacom. Received by courier the modem, I am not a technician, try and ask call centre to sent a technician out seems to be difficult to understand. No Wiffi no customer service yet. Don’t ever get Vodacom Wiffi
