Impossible to get through! Chat also doesn't work.

I have been trying to get a hold of Telkom for hours. Literally have to hold on the phone for an hour before they bother to answer. My ADSL line is not working as it should. There is a billing error that needs to be taken care of before my line gets switched off and I need to move my line to my ADSL provider because dealing with Telkom is beyond ridiculous. When I eventually managed to get through I was told that there is a serious physical problem on my line. I have reported this numerous times before but nothing is done and I am getting quite irritated with this. Can someone competent phone me to sort my issues out please? ***.
