Telkom VERY POOR SERVICE

We have a telkom 2mb line, we have been battleling with them now for 8+month where the line is extremely slow (350ping) and everytime we phone them say there is nothing wrong with the line.<br> And when a technition comes out he says it is imposssible for the ping to be that high even though we show him pictures.<br> They are now forcing us to upgrade to a bigger line! WE pay for a service that we are not getting and only getting a line that is practically useless.
