Vodacom false advertising -Carte Blanche to investigate

Vodacom is beyond scrupulous. They market products and cheat customers into paying what they have not agreed to. We have been complaining and trying to sort this out for 2 years now and every time they say "resolved". But nothing is resolved, we are still being charged for what we have not agreed to. We have the recording as well. If this is not resolved now, we need to take this further and maybe Carte Blanche can investigate as we can see from reviews from other people, that this has also happened to them.
