Unwanted charges

<p>I have been with Vodacom for years and I am loosing faith in them recently. I put a limit on my contract last month and I exceeded it and this month the same. I have been charged for out of data bundle rates when I still have data available on my account and now I see I have been charged for vodacom live which I dont want. I tried to unsubscribe and I get a web page error so even if I wanted this app I cant use it.</p> <p><br />I want to know why I can put a limit on my account and it still goes over and how do I get rid of this stupid subscription which I didn't want.</p> <p><br />I have tried your call back system twice and get an error and sat waiting for your call centre for 30min then getting through then I get cut off twice.</p>
