VODACOM Disgusting non service

On the 18th of July it will be a month since the start of the upgrade and still i have the phone Vodacom needs to collect, still the upgrade cancellation has not be done. But my account has been charged and no one is answering my emails or phoning me back. Or trying to finalize the problem. All i wanted was to change to the correct package that suits me. Really annoyed and angry with the lack of service, lack of customer care,.
