From bad to worse

We have 4 cell phones on one contract We now need to upgrade the one cell phone Tried doing this online and via the call centre Unable to get any assistance as it states our account is behind. The amount its behind is the exact amount that is only due the end of September. This is ridiculous and outrageous. We have been with Vodacom for years and the service is going from bad to worse. All over you hear of people getting gifts from Vodacom and we who are paid in full customers gets *****ed over evry single time Vodacom you need to get you service solutions back in line or must we start using the r word.
