Not repairing faulty landline and ADSL

My Telkom landline is not working at all, and my ADSL connection has intermittent connectivity problems. I have repeatedly logged calls on Telkom's system, and each time I receive an inquiry number. <br> <br> Each time I get promised that a technician will attend to my fault within 2 days. This does not happen. I have never had anybody come out to my premises. Every time, without informing me, Telkom closes my fault and indicates that it is fixed on its web site, except it is not fixed, and in fact, Telkom didn't a) do anything, b) send out a technician, or c) attend to the problem. Furthermore, Telkom sends me SMSs saying my phone bill will be reduced, but it has in fact increased - for a service they are not providing.<br> <br> I have also tried escalating the problem on their web site but, needless to say, Telkom doesn't respond to me at all.
