Vodacom is so in professional

I'm soooo angry and upset with Vodacom. I have been struggling since December to sort out my account and our lines are disconnected each time. It is really frustrating explaining the same thing over and over, raising dispute after dispute and it just gets kicked out and the solutions department states they are correct. I also work in accounts and it's definitely not. They keep on billing us incorrect and we constantly have our lines cut for their mistakes. I have never had problems with them in the past and we have customers for more than 10 years. I have gone to the Vodacom centre in Bellville and I have called customer care & solutions department over and over but still nothing happens. I'm so done and dissatisfied with Vodacom right now. Im going to send and email to a director or someone up in the ranks maybe then my voice and disgust will be seen too.
