Pathetic non existent service

We have been experiencing internet issues since March. Vumatel confirmed our line needs re installation. In this time frame we have had no commitment and MWEB have disconnected our service twice. According to vumatel there is no product on the line. According to MWEB our line is active. Yet we get to shop.vumatel everytime we connect to the router. No one in MWEB, including the head of products cannot help us. They are not interested in resolving issues. How hard is it for an ISP to provide a working line? Its not like Im asking a plumber to wire my house
