Fiber consultants never answer their phones from VODACOM

I am now dealing with the 4th or 5th person in connection with fibre and non of them call back and answering their phones is an option they chose to ignore. Fibre has been installed in my complex. I signed a 5 to 15 day installation agreement on 15 November. Since then I have been in contact with 4 or 5 women. They promise me answers within 5 mins by calling me back. This never happens. I call up to 10 times a day and they never answer their phones. Seems Vodacom is okay with this complete lack of service. After over 2 months I was promised installation last Thursday 18 Jan. Then they disappeared leaving my furniture all over my lounge, never to be seen again. My contacts at Vodacom never answer their phones. NO SERVICE FROM VODACOM!!!!!!
