Repeated problem with data not being uploaded as per contract

<p>I upgraded my contract with Vodacom South Africa in January 2016 where as per upgrade offer I was given extra 1GB data per month on top of what comes with S-plan for the term of contract (24 months). Repeatedly i have not been provided this extra data unless I have sent them email/called. In September again I see missing data. After complaining I was told my 24 month contract expired in July 2016 that is why I am not getting the extra data. So as per them in six month my 24 month contract has expired. On pointing this out, my qurey apparently has been escalated to the upgrades department on 26th of September. I am yet to hear anything so far and I keep paying the contract amount without receiving the serive. This is blatant theft and Vodacom surely is not going to be receiving my business once my contract expires. </p>
