No Customer Service From Vodacom

I'm so dissapointed in Vodacom, on a business level and a personal level. Together we pay Vodacom almost R8000 a month. The service we receive in return is shocking, yet there is absolutely no platform where we can complain to. I've phoned customer service yesterday, too many times, therefore I was told by the automated voice on the line that Vodacom will phone me back. Needless to say, I'm still waiting. Not to mention that the call dropped twice when I finally got through to a call center consultant and was never phoned back. Out of frustration I phoned my nearest Vodacom shop only to be told: There is unfortunately no email address you can email a complaint to and a consultant WILL phone you back the same day. I'm still waiting ???
