Poor service

We have been without signal or Wifi for 4 weeks. Both myself and my husband have phoned to report and phoned to follow up, customer care cant help as they are sitting in Johannesburg, no one can give us top management contacts in order for us to take this matter higher. We are on a farm we have no Telkom lines in our area, which means we are vulnerable and rely on our cell phones. We cannot do our banking or anything on the internet, make phone calls etc, but yet Vodacom are the first ones to deduct our payment every month.
