FAST INTERNET SLOW SERVICE!!

In Feb 2015 we app**** for a business OPTICON system with Telkom business we received our lines 3 months later at that point I asked the technician if he could install the ADSL as well he informed me that he only installs the telephone lines. It is now MID Aug and I still have no internet at my office. I have had numerous technicians here telling me they need a cable and they are not in charge of installing this cable. I have phoned line management, call center and sales people all of them telling me it's not their responsibility. I receive an sms telling me a technician is on its way the guy pitches and tells me its not his area??? Others tell me the cable story again...all I want to know is will TELKOM install my internet or should I make other arrangements.<br> Fastest internet in SA?? Very slow installing it??<br>
