Vodacom depleted Data

I just had my 4 gigabyte depleted within a week, phoned customer service to find why is that the case and argued it was against ICASA ruling to deplete data and the call centre agent was quick to dismiss my complaint and in not exact words but basically told me you failed to use your data now its all lost just deal. Just thinking about how much money we spend on the network with partner and to be told such nonsense made my bowels turn and made me reconsider other networks. For instance with TelkomSA I wouldn't be experiencing such ludicrousness. I'm angry to say least
