Service is shocking once again

<p>I had a vodacon contract that was due for an upgrade, vodacom staff called me to do an upgrade but i had cancelled. But now i tried to get a new line and its denied????? How does that work?</p> <p>I have had nothing but bad service from Vodacom.......my bill was always 400 - 700 a month and was always paid but a small 199 prepaid contract is denied. I dont understand at all! </p>
