No service from Vodacom

We have the installers of Vodacom Fibre at our home. Right this minute. We showed them where to drill through the wall so that they do not disturb any other wiring. What do they do? Drill straight trough our CCTV system’s wiring. Logging a complaint with Vodacom while they are here has proven difficult. Being cut off many times. After being promised a manager will phone me now an hour later nothing! Even on their FB page .... nothing. Now I know its early days but with these things if you dont complain immediately they wont do anything about it and will plead that you did not inform them. However getting to even lodge a complaint with them is proving impossible! Really bad service. After I have been with Vodacom for over 20 years this is what we get.
