ADSL installation reschedule on due date

<p>Telkom scheduled an installation date to install our ADSL line on the 28/12/2016, which we app**** for the line on the 18/12/2016. I put a days leave for the 28/12/2016. So on the 28/12/2016 at 9 in the morning I get a SMS to mention my line installation has been rescheduled what nonsense is this. I go to the Telkom store no one can help me. I phone the call centre which no one can help me again. What disgusting service is this. I want my installation on the 28/12/2016 as promised.</p>
