Not contacted by Vodacom after Notifying i was ****** by them

<p>****** again by Vodacom My contract came to an end a few months and I phoned vodacom and cancelled it . I looked at my bill this month and realised that Vodacom has been charging me for another contract (over R200.00 per month). I phoned the helpdesk (111) several times and have been pushed to various departments with no-one capable of assisting. I need Vodacom to cancel this contract immediately and reverse any charges incurred. I have not signed any documents for a new contract nor have Ireceived a new phone. How can they do this. How many other innocent people have been exploited like this?</p>
