Vodacom false advertising

<p>I signed up for a contract with vodacom which was suppose to cost R399 per month. They now charge me over R450 per month because apparently their advert pricing doesn't include vat! On enquiring they agreed that the advert doesn't mention anything about Vat and logged an inquiry to resolve. I since heard nothing back but got credited R299 for I'm not sure what. But thy still continue to overcharge me!</p>
