Incorrect billing on Vodacom account

<p>Since 5 Sept 2016 i'm trying to sort out challenges with Vodacom, but to NO SUCCESS.</p> <p>Have logged calls with Vodacom and have sent numerous emails, but to NO SUCCESS.</p> <p>Vodacom keeps on billing me for an upgraded contract which I have CANCELLED !!!</p> <p>Vodacom did reply to me today, but they did not sort out the problem on my account.</p> <p>They don't read my mails with understanding. They just follow their own opinion.</p> <p>This is totally unacceptable. How much longer must I wait for a competent person to assist me?</p> <p>This is really POOR service from Vodacom staff members.</p> <p>I am very unhappy</p>
