2 Weeks and no feedback

After waiting 6 weeks to have an adsl line installed the line gets installed but does not work. I have reported a fault with the technician that installed the line as well as the call centre yet 2 weeks later i still do not have the capability to use to the internet. The fault has been escalated yet nothing has happened. I have been **** too, promised call backs as well as a promise that a technician will be at my premises 2 days ago and still no one has arrived or bothered to call me. Currently someone else is connecting to the internet via my number and Telkom does not feel that that is a problem. Some other person has the ability to use my adsl line yet i am the one that must pay for it. I am completely an utter disgusted with the service. I mean what type of company says that they cannot get in touch with the technical division so that i could speak to the technician or even supply me with the contact details of higher management. This is highly unacceptable.
