Failure to provide for a paid service

I live in westham unit 12, Phoenix. I have on several occasions called and discussed the poor signal connection in the area with the call center. To date no response, no feedback. There is a problem in the area that vodacom is well aware of as all my neighbour's have the same issue. We are paying for a service that is not being provided. Calls get cut off, phone goes straight to vmail whilst on, Don't even try to switch on your PS4 VERY BIG MISTAKE. Loads all the time never get 4g signal. However leave the area and there's no issue. I need a fix to this issue or unfortunately I will persue further. Failure to provide for a paid service. It's utter ****.
