after years of complaints and still no network

i have been calling Vodacom's call centre alerting them about a problem with their network, my plight was then escalated to their seniors and I never had a response from them ever. the problem I have in the area I reside at is network and only Vodacom's not the other networks. I was told that there is an aerial that Vodacom is erecting close to where I live but still no network and some times it come only at 20% max and nothing more, others are readily available at 100.10% all day long and everyday. when I called Vodacom one lady said \why don't I join those networks then? because it should be free"<br> I am writing this complaint today and I still have the network problem. I told them that I am a student and run a business from home"
