Vodacom still sucks

I thought that after you speak to someone with some authority within Vodacom that billing problems would be sorted out, but even with assurances they still can't get the left hand to talk to the right.

Now I guess, because they won't be receiving payment they might see fit to sort out the problems I'm having
