Telkom - where is the service?

For the last 3 months my land line has not worked. It's dead to the world. A technician came to investigate in December and told me it was a cable fault and to contact a cable technician. The cable technician advised that the cable needed replacing and that it would cost me almost R6K. Why is this cost for my expense? I have since been going back and forth to the Telkom lines to report a cable fault and that it needs reporting and fixing. Each time there is a different reply. Either the fault is not logged, or the reference number a has been cancelled or the fault needs re-logging etc etc. and so it has been going on since November! and I have no working line
