Vodacom not following through with promise to rectify errors, repeatedly told they will call me back but they do not

<p>I was informed by Vodacom that the reason all my contract airtime disappeared by the 4th of September was because the 10 GB promotional data bundle that I received as part of my contract upgrade expired at the end of August - after one month in other words - and so I was paying out of bundle rates for internet usage. After discussions with their customer service and their data department they agreed to refund me the airtime but this has not happened. My complaint remains, the fact that the 10GB had a limited shelf life was not made obvious at any point when I upgraded. I checked my balance on 12 July 2016 and got an sms saying I had 11.47 GB valid until 15/09/2020. </p> <p>I have been shunted from pillar to post calling them, told to speak to the team leader (Brian) at the service department, that he would call me back, he has not, put on hold indefinitely when I called again today.</p> <p>I am really tired of the appalling service I have recieved from Vodacom and am seriously considering taking this to the consumer complaints commission next.</p>
