Just Another Scheme To Attract Customers?

My contract was upgraded on 23rd December 2015. The deal telkom offers has unlimited data until the end of March 2016. I still have no data almost a month later. The store that my upgrade was done at shows me details have been processed. When I call the call centre I'm told that the store has done something wrong. After numerous visits to the store and calls to the call centre, I was told on yesterday's call to the call centre that they're logging another complaint to their \back office"- whatever that is - and given yet another reference number saying that it would take 72 working hours to get a feedback from them. And that's just feedback"
