Instalation 6 weeks late!!! And still no solution

I went to Telkom on 20 July 2017 while on leave to get my mom an ADSL line put into her house. The Telkom shop was ridiculous, we waited 2 hours for the 3 people in front of us to be served. Then we ask if they can convert my moms phone line to an ADSL line, the lady says this is not possible but they can put in a new line rather, we agree to do this. I only get 2 weeks leave at a time so I asked if this would be done before I left and the sales agent guaranteed me installation in 7 working days.... That was the last I heard... until yesterday.... 7 September 2017 (Yes, nearly a whole 2 months)!!! A technician arrives at my moms house despite her already making alternate arrangements for internet with a better service provider and then tells her that they cannot put in another line, why didn't she want to just upgrade her line.... which was what we wanted to do from the start. Then he left. Who knows what is going to happen, I am just glad 3g prices are so cheap now so this company cant hold us ransom anymore. THE WORST SERVICE IN MY EXISTANCE!!!!
