Useless to call callcentre!!

I suppose no one from Telkom will read this... Yesterday we encountered a problem with our ADSL Router, after phoning 10210 six times, and listening to the ear numbing tunes and possibilities of problems via recording for 15minutes, i got hold of an agent. After switching on and off...on and off, and resetting the router, she decided that it would be better to get an technician to come and sort the problem. After a while i did find the problem myself, and tried to get hold of the call centre again to get a username and password for the router because it was set back to factory default, now this was about 20:30, after listening to the recording again for another 11 minutes, someone just picked up the phone and hanged up again, I tried again, for another 13 minutes, SAME STORY,picked up the phone and hanged up again.....It seem that if it gets close to going home time, they just pick up and immediately hang up the phone to prevent them from going home later. This is extremely unprofessional, and a waste of airtime. Why doesnt telkom just shut their doors? They have no customer service, the service delivery is poor, signal isnt trustworthy at all....
