Missed arranged installation date

I have arrange with Telkom to install a line at my house for ADSL. The arranged date was 2016-01-15, then they changed it on short notice to the 2015-01-14. To no surprise, the technician was a no show without any notice or explanation to why he never showed. He also did not call to tell me he will not be coming. I called the help center and was given a reference no. (808439) after having to wait 45 minutes on the phone being shoved around through different service departments. I still don't have an idea to when the technician will come since he missed his ARRANGED appointment, which I have numerous confirmation from via SMS.<br> <br> Super bad service and correspondence. <br> <br> My order number ***<br> Ref.
