Possibly the worst service EVER

I have been trying to get DSL at home for over a month now. Eventually a line was installed, and so I thought it would we the end of waiting. Tried to set up dsl, but was told i need a username and password, that should have been msged to me but a lady from telkom that phoned me, who didnt even know yet that the line had been installed, she transfers me to someone she assures can help, the person i get transferred to say they will call me back...no call back!. Call through to the call centre the next day, was hung up on after 5 minutes of waiting, get through to someone the next time who says they cant help me, but the technical department can, hold for 5 minutes, technical person says they cant help me, will put me through to sales, wait 10 minutes, get hung up on. Does anyone at Telkom know how to do help a customer???
