Pathetic service from Technical department

We have taken the unlimited deal with telkom. When we have been trying to configure the router is has been unsuccessful .Eventually we have been told the line is not syncing and a fault has been logged on the 08 Jan. I had phoned on the 18 Jan and was told that a technician has been assigned the consultant had put me on hold then came back and said she phoned the technician has said he will phone me. At 6.30pm i had phoned back as i have not heard anything yet, i am now told that the line has been tested and there is no fault. But the consultant herself told me that she can see the line is not syncing. On friday i called its a different story that its still in progress and no technician has been assigned . Who do we believe and how long more must we wait for the line to be sorted. This is unacceptable and very frustrating. We have canceled our internet service from another service provider to take the deal from telkom but now we are rethinking as we have taken the service but cant even use it.
