Vodacom Fibre installation

I signed up for vodacom fibre in June. I was advised that the fibre would be installed early August. When I spoke to vodacom the first time after waiting a month they were not even aware that the fibre has not been installed in my house. A month since installation should have been performed, two weeks since I have started following up, more than 5 times following up, messages, calls. Nothing has been done to resolve this, only promises to follow up but no responses
