inabality to repair

On three separate occasions I've reported my line as faulty. Every time a fault is created and resolved approximately a day later. And yet I'm still getting no better than 4Mbps on my 10Mbps line and the line still drops on a regular basis. At the back of my property the cable that runs from pole to pole has a tree growing against it creating additional tension on the line. This was noted by the first technician who installed the line and was reported to Telkom. Nothing has been done about this. Please replace this cable as everything else Telkom has tried has failed to make a difference.
