Worst service ever

On Tuesday Telkom came out to install a line, in the end they did not have to,install a lone because there was one already. I then asked the technicians if the lin eis connected and ready to use, as I need to let our ISP know so that they can activate the internet. The iSP company then told me that our line is faulty, shows DN is invalled error. i then phoned Telkom and they put me through to 3 different *********** people, no one could help me. 2 Ladies from headoffice then phoned me to ask about the line and when I told them it was faultythey almost immediately put the phone down and told me they would get back to me. As till today NO ONE has gotten back to me or fixed the line. I have to run a business, but cant start because of Telkoms *********** people that work for them and their bad customer service. Why do we in South Africa have to put up with such bad service and *********** people....
