Absolutely no customer service!!!

I app**** for a Vodacom Fibre line on 4 January 2019. After I made appointment online no one showed up. I called Vodacom to rebook an appointment, the lady assured me a booking was made for the next day, and again no one arrived the whole day. A week later after calling again to make another booking, Vodacom finally arrived, just to be told that they could not complete the installation because the fibre line had broken and maintenance needed to be called in. I have called Vodacom EVERY single week since 8 January with call agents either dropping my call, having no information and saying they will call me back- and NO ONE EVER calls me back with an update. Vodacom is the only fibre provider in my complex and I am currently using cellphone data to keep my office going. This is costing an absolute fortune. Please can you tell me who I can contact to help resolve this issue. It is so frustrating being put on hold for ages just to be hung up on. I cannot waste my time, and airtime anymore. I cannot say Vodacom’s customer service is bad, it’s just non-existent.
