Installation of new telephone/ADSL line

I made an application for a new line at the beginning of September and asked that the application be prioritised as my son needs internet to write his exams. Only when I called to find out what was happening 2 weeks later, was I told that installation was scheduled for 9 October. The day came and went and despite being assured again, telephonically that the installation would happen yesterday, it didnt. No communication from Telkom. I called again this morning and was told there was a technical problem and so the installation would happen today. I called again after lunch to be told that the first available date for installation is 23 November. This is absolutely unacceptable. Why should we have to put up with such shoddy service from Telkom?
