Telkom will not respond to my installation order

I had an appointment to have my adsl service migrated to my new adress on the 2nd july. I instructed the person logging my installation order and a call centre operator on 2 separate occasions that the technicians must call me before they arrive at my address so that I could make arrangements to meet them. Of course this did not happen. Now it is a week later and as much as I try to get clarity as to when I will have my installation done I am getting absolutely no response from telkom. I resorted to walking into a telkom direct store in canal walk to try to get this resolved edwin initially helped me by putting me in contact with Reuben ward his manager. However Reuben is ignoring my emails. I need this line installed immediately.
