Failure to install home ADSL LINE

Telkom failure to install home adsl line. Order no ***. Two technicians have arrived on separate occasions. Always pass the buck to someone else and fail to do the installation. I keep telling the call centre the installation can only be done on a Saturday but they keep sending me SMS to install the line on a weekday. I want the whole agreement cancelled. Sent through cancellation request. No response.<br> Terrible service. Call centre unhelpful. Cannot speak to a supervisor.
