Tekom do not keep to their install dates

I ordered an ADSL line on the 4th February I received an sms telling me it will be installed on the 10th February 2016 between 7:30 and 12:00, I also received on the 8th February telling my to have my ID and cerified copy of my ID ready. But no one has come to install the line. I phoned customer care *** but no one could give me an answer, it seems to me that Telkom Customer Care do not care. <br> <br> Harold Price<br>
