Horrible service from Vodacom

<p>Last Sunday I went to get a reuter from Vodacom shop in Westgate mall in Roodepoort. I was told that the sim card would be active after 4 hrs but till today it is not active. When I called their customer centre they have been telling me it's active but yesterday I discovered that it is not active and I went to the shop in Rivonia they did a couple of things and told me it would work after 4 hrs but nothing. Today I called the customer centre and they told me they couldn't help me I need to go back to Westgate to get them to activate it. I called Westgate and they told me they have activated and I must try after 4 hours but still nothing. What can I do to get the sim card activated because I can't do it myself and Vodacom can't, so what's the way forward?</p>
