TELKOM can't deliver

I moved to Midstream Estate in Centurion 2 months ago. Since I often work from home the obvious thing to do was to have a Telkom ADSL service installed in my home, so after I moved in I contacted Telkom and placed the order, which was already a MISSION since they don't know 'Midstream Estate'. Eventually they found my correct address and the order was placed. Imagine the disbelieve when I was informed that they only have 4MB lines available. Then came another call and I was informed that TELKOM DOESN'T HAVE ANY ADSL LINES AVAILABLE IN MIDSTREAM? This is an estate with + 7,500 high-end homes and Telkom can't / won't deliver service here? Did they make a deal with the local wi-fi suppliers hoping they'll make more money or is someone being bribed not to deliver service here? This again shows that SA is in need of another fixed line service supplier.
