ADSL Line Installation - Promises with no delivery

Telkom have arrived at my house on two occasions (*** & 29/01/2016) to install my line/ADSL. After the second visit they promised everything would be installed by 2/02/2015. After - I was informed that I would have to wait until the 2nd of February because they need to insert a poll etc. I have not heard from Telkom today. I was worried that this may happen so I called the call centre this afternoon to confirm a technician will be dispatched - again I was promised they would arrive before 4pm. I have left work on two occasions to meet with Telkom and now a \no show\"? Is this normal for a telephone line/ADSL installation? Multiple call outs, poor communication, bad service. "
