No Vodacom Fiber from three weeks, technicians

I have been using Vodacom for over 18 years, I am so disappointed with the bad service I have received as a paying customer. I have been without Vodacom Fibre for the past three weeks and we have spent over three thousand rand for the entire family in the past three week. I have been calling the customer care to report almost everyday and there is a new story. Technicians claim to have called me but it is not true. I have left messages indicating with consultants that I need technicians to come and check but there has not been any action for the past three weeks.
