Telkom not converting lines in the promised time

I am a new users to telkom and I have not been impressed at all, we asked the consultants firstly that we wanted an internet line and only a normal telephone was installed. We then had to go back to telkom and wait in the ques for over an hour before getting helped. We eventually got them to add a dsl line onto our telephone line and were promised that it would be activated in 48 hours. It is now 120 since they told me that and still no dsl line!! As a student I require the internet quite often for final year projects and I just have not been able to do anything because of this! I am thoroughly dissapointed as I thought that telkom would have been better than this!!
