Shocking Service and still no ADSL

I app**** for a telephone line and ADSL in February for the sole purpose of having internet so I can work from home in the evenings. After Telkom installing the telephone line at the wrong address which could have easily been avoided if the technician had just phoned before like I was told they would and not just rock up whenever they feel like with no warning They eventually cancelled the incorrect line and came and installed a new one at my correct address still with no warning an the technician just rocking up without making a call first to let me know they where coming luckily I was home that day. Now I have been waiting 2 months for them to activate ADSL on the line the whole time with them trying to charge me for the both lines the incorrect one and the correct one they even added a charge for canceling the incorrect line without a months notice EVEN KNOW IT IS THERE FAULT. Now they are telling me there is no ports available and I cannot get ADSL on my line. they cant tell me when or if even I ever will be able to get ADSL which seems crazy seeing as I live in the center of Cape Town with businesses all around me. I have never heard of this before.
