Did not do what I paid them for!

I did an upgrade yesterday. I spent over an hour in the store. I asked the guy to make sure that I have two simple cards working on the one number. He said he would set it up and that I had to pay extra for him to do so. I did this. He then said within 24 hours both simply cards would be working. <br> It's over 24 hours and the second card does not work. I called the call centre only to be told the second aim was not activated!<br> Vodacom took my money, **** to me and Di not do what they promised!
