TELKOM WONT REPAIR MY LINE

Two weeks ago we hooked up an ADSL line with Telkom, we have had problems from day one. When we first called Telkom they advised that the problem is not with the line but with the ISP, when we called the ISP they said there is no problem from their side, we then called Telkom once again and they then advised that fault is not with them but with the Modem we are using, we have changed the Modem twice on Telkom's say so. Eventually they admitted the problem is with them and that they would send a technician out this was Monday the 15th after two weeks of problems. <br> Since Monday the Technician has not come through, when I call they keep telling me that they are testing the line remotely (they have been testings the line remotely for three days now). <br> No one can tell me when this Technician will be coming through, we are a business and have been without internet access for the third week now.
