Telkom refuses to fix my ADSL line

I have been having a problem with my ADSL line since January 2015 whereby I am getting intermittent sync. I have reported it numerous times and they keep closing the report without actually resolving the problem. I then have to spend an hour or more on the phone to report the fault again. A technician came out once and said I have faulty wiring which was installed in the bathroom by Telkom and he needs to speak to his supervisor about moving the line to another part of the house and then went away and once again closed the fault report. I never ever heard back from the technician or his supervisor. I don't know why they don't want to come and fix the wiring. I didn't install the line myself and I am not a technician so I can't fix the line myself. What am I supposed to do? I hate Telkom so very, very much. They are all a bunch of apathetic work dodgers judging by my experiences with them. I wish there was someone else who could provide my ADSL line. I would drop Telkom in a heartbeat.
