Vodacom, how many customers must you loose?

I've made countless complaints about the poor service, many complaints about the internet speed, even let everyone know you blocked my number from canceling the account. I have even raised my complaint on Twitter but still, Vodacom refuses to give up the few hundred Rand's a month they can **** out of me. How many other people struggle with this provider I wonder but can't speak up because it's a waste of valuable time. Vodacom, it's time to hear what customers are saying. Resolve issues quickly, where you can't, admit defeat and cancel the deal. How can a person be expected to pay for such poor service?
