Horrible service ! Frustrated!!!

<p>I am on a Red Advantage contract, and have been over-billed by Vodacom numerious times. </p> <p>I've been helped at The Rivonia Village Branch, by friendly staff, but 3 months later nothing has been done, and I Have just been billed for 10 Gigs of data that I firstly, did not buy and secondly an "outstanding bill" that I paid last month, that was brought forward. </p> <p>All advice I get is to phone the call centre. And to date,nothing has been done, even though I've put in numerious calls and complaints...</p> <p> </p> <p>Please help!</p>
