Vumatel Line Activation Problems

I have been struggeling for almost a month now getting my line activated. The problem at hand is that Vuma can't seem to find my address (they have in fact installed a Vuma box within my house, but they say my address does not exist). After many calls and emails, I constantly repeated my address and they just went on and used the closest address that matches my street name. So they activiated the completely wrong house, which is why my wifi can't connect. Thereafter I contacted them again to say that the address they are using is incorrect, but they went ahead anyway. I have been sitting for 30 days now without wifi. My ISP provider confirmed that my address (the correct one) has not yet been activated, which is proof that Vuma activated the wrong house. I dont know how many more times I need to repeat my address. And whay do they mean my address does not exist? I am living in the house, is that not enough proof?
