Installation of ADSL line

I app**** for an ADSL line on 6th January 2016. Today is 27 January and my ADSL line has still not been installed. I had an a[appointment with them for the entire day on Friday 22 January, and therefore took leave from my work in order to be there when the technician arrived. By 13:00 I had not heard anything from them and phoned the call centre, who confirmed that this guy would be there before 16:30, again nothing happened until 15:00 when I made another call to Telkom to make sure that the line would still be installed, they reassured me again that the guy was on his way. However at 16:00 the technician phoned me to say that he didn't check the morning and accidentally left my modem and could therefore not install it on the day. unfortunately I had used up my leave, and a whole day was wasted.I explained this to the technician and he said he wont be able to do anything as it is late. I was still busy explaining my situation when he put down the phone in my ear, extremely unprofessional. I phoned back, and he would not answer. I phoned another 6 times and every time he would reject my call. This is unacceptable service, I am disappointed in Telkom, and now still have no internet.
