No communication/response after installation

I had a technician come out to my place to put in a land line so that I can activate ADSL that I purchased from Telkom. I was not there as I was away but he said he was there and was going to install it.<br> <br> After that I never heard anything again from Telkom. No confirmation that the line was installed and that everything is working. I got to my place and could not connect as it looks like the line has not been activated and now I have been trying to get hold of them for 2 days straight and the phone just rings as they never answer it. I find this to be very bad service and cannot understand how you not let a customer know that the service has been performed.
