Vodacom ******* practices when it comes to cancellations

To cancel an account with Vodacom has become out right ********. 2 months before the account was due for an upgrade, I went into one of their branches to cancel the account. Firstly they no longer cancel accounts from the actual physical branches, you need to do it online now, so I did. Surprise surprise, the account was not cancelled and I was billed again. Now every month I phone in to cancel and request a refund on the additional months I have been charge, but even after time they assure me all has been done and said, the next month rolls by and I'm charged again. If they haven't done the cancellation and refund with interest + bank charges incurred, I will be taking them to court, since that is the only thing that seems to get them to do something is when threatened with legal action.

Besides the contract with the 3GB data account which they can't seem to cancel, they still haven't even bothered to fix the voice on my original account, since you know, having voice to voice within only Vodacoms network is pointless!
