Too far from the exchange

<p>This is not so much a complaint as it is me trying to figure out why I cannot be moved to a closer exchange. My main problem is that I am currently paying for a 10 Mbps ADSL line, but I am receiving 6 Mbps speeds. This is not an issue at my house as I have tried every possible fix there is. I've had technicians come out to have a look and they informed me that the exchange I am connected to is too far from my house. I have contacted Telkom numerous times over the past few months to figure out why my line cannot be moved to a closer exchange, only to be told that I am already connected to the closest exchange, which according to Telkom is about 4km away. I just find it hard to believe that there is not a single exchange closer to my house. Is it possible to see a geographical map of all exchanges so I can get some peace of mind?</p>
