Faulty internet

We live in Sezela in KZN, and run a small business from home. Our business is phone, internet and email dependent. We have endless problems with our phone and our internet is up and down, as I am typing this, our phone is just static. We have had 3 hours of downtime today due to intermittent Internet. Tried calling Telkom about it and they are not interested- say we need to wait for a moth before they can do some sort of analysis on our internet , and they refuse to escalate it to someone higher up. When I call, all they do is reset the ports. My wife even spoke to some or other manager who made it quite clear that he was not going to help. Is this the type of service Telkom offer? It has been an endless problem for over 2 months. Why are Telkom not interested? I am sick and tired of being pushed from pillar to post with no results. I would ask Telkom to phone me, but the line is too bad and they won't hear me.
