Vodacom are billing for FREE data

<p>I upgraded last year October and with this received a free tablet with 250 mb data. First month I did not get billed for the data as is free. Since Janunary I have now been billed for this data. I have tried going into a shop 3 times and multiple queries logged with Vodacom. I am still been billed for something that was free. I have never met such a useless organisation in my life. Check your bills as I am sure I am not the only one been billed for something I should not be.</p>
