Contract upgrade

<p>I have upgrdated my contract in January 2017 and the contract included 10 GB of data for 24 months. In addtional to this, I was promised an extra 20 GB monthly for 24 months. The reason for this was that MTN was giving out 50 GB per months specials and Vodacom went for a similar thing. It is now March 2017 I have only recieved 10G in January 2017. I have contact custumer service, upgrade deparment and ths strore, all of them they are shifting the responsibility. I am powerless and my next step is go to the South African Consumer Commission. This is not on!!!</p>
