ADSL and Fixed Telephone line installation

I ordered an ADSL and telephone line from Telkom in April. After paying the requested deposit of R700, I did not receive any feedback from Telkom, eventually a technician came to install the products I acquired. Upon him arriving at my house, he advised that he cannot proceed with the installation due to there being no telephone line of which telkom will need to come and put one in. Nobody has contacted me since and this was a week ago. I would like to know when Telkom will come and put a line in and how long it will take. This is terrible customer service on Telkoms part!
