I dont think telkom are capeble of installing "gold lines"
In south africa they would get stolen and melted down to remove the small amount of gold which is in it...
Had Telkom Techs out today but they couldnt find any faults - fact is though, that they dont have a proper DSL tester. "a tester is to expensive to supply each area with one" is what management apperantly say- so no tester for these guys!!!!!!!!!
In the end I was told that ADSL is a "best effort service" so what you get you get - tuff luck buddy!!!
