Vodacom Airtime Disappearing

I just wish to mention my frustration yet again with Vodacom. In the last communication they stated that my matter was resolved but I have seen nothing as such. Reason been that said they still debiting my account the amount of R123.99 for two years without giving me any Airtime as agreed. They promise to call me, but nothing has happened up until now. This continues I would have no choice to take the matter forward and thereby involving the courts.
