No Service from telkom since 2nd Dec 2015

I run a small computer shop with internet and fax service as well. I have had problems with my line since the 2nd of December 2015. I have a major noise on my line that cause my internet to drop constantly, most of the times no connection. I cannot fax because the fax fails because of the noise. I am losing a lot of clients now. I managed after 15 days to get a reference number out of Telkom. That was on the 17th Of December. On the 24th a technician came here and spend the whole day smoking my sigarettes and drinking my cooldrink and not a damn thing was done. Keeps on going to main box and back to my shop, meanwhile asking for sigarettes every time. I tried to please him because i am desperate. He told me it was late (around 15:00) and he will be back after Christmas on the 28th. He never came back. Instead i get sms from Telkom stating my line is fixed. I rep**** NO it is not fixed. Try and get hold of a supervisor or manager, they keep on telling you no one available. No Service and no one wants to help and no way to get hold of any type of management. All telkom website number all link to 10210, no way of contacting their HQ to speak to someone in charge. I lost all hope.
