Charged for ********** Line

<p>I don't know how many times i have to keep on telling Vodacom to cancel</p> <p>the *****lent line that was upgraded on my name. i have spoken to them on several occasions regarding this matter it still has not been resolved. they promissed to cancel the line and credit back the money i have paid already on the line. I keep receiving calls now that I owe R2592, how am I supposed to pay for something i didnt use?</p>
