No Service

I have been trying to have a Telkom ADSL line fault sorted out for in excess of 3 months through Webafrica. The first technician sent said there was nothing wrong with the line and left within 10min of arriving. The second technician was part of a team sent from the eastern Cape to attend to faults that Bellville just was not attending to - after more than an hour of checking both at my home and the exchange he advised that there was definitely a fault on the line between the house and the exchange and advised he would escalate the problem with his superior. That was more than 2 months ago and we have yet to see any change. Another call logged with Webafrica two weeks ago was followed with promises of another technician being sent out - he has yet to arrive. What do I have to do to actually get the line repaired so that my internet is usable. I have 4meg line but only get speeds 1.5mbps if I am lucky! At present Telkom scores 0/10 for service and delivery. Is there anyone actually working at Telkom?????
