worse customer service

<p>I have been due for an upgrade in July 2016 with Vodacom, I had submited my cancelation request to Vodacom in advance, when it got close to the date Vodacom had offered me a deal which I had accepted and I continued with the contract, on the first of the month I was promised data plus airtime on that deal, I had received the airtime but not the data, when I called Vodacom they could see on the system what I was devoted for and not but could not help me since then, my initial call to them was on the 4 August 2016, I have made another call to them a few days later, and since then no response. I have requested my contract be cancelled now as a breach of contract, there isn't anyone calling me back. When I stop payment to the account they will then hold me liable . </p>
