HOW DO I GET HOLD OF TELKOM FOR ANY SERVICE AT ALL

I have been trying to get hold of Telkom to get a new ADSL line installed at my house since 6 February 2015. I have phoned 10210, their Fourways branch, their Sandton Branch, their Cresta Branch, their Rosebank branch AND i EVEN Emailed them - NUMEROUS TIMES!! Firstly non of the branches even answer the phone, and they haven't even responded to my mail. How am I supposed to become a new customer to them if I'm not even sure they will respond to any of my service queries in future?? I have even thought of paying double the amount just to go to the opponent as they at least answered the phone!! This is ridiculous - I have started my studies already and still have no ADSL at my house - I'm sure Telkom won't be paying for the assignments I am missing because they are too lazy to pick up the phone and get new business. I am very dissapointed as I knew in the beginning I would struggle to get service from Telkom, but I had no Idea that I won't be receiving ANY service.. Where do I go from here?
