Upgrade of adsl line results in no internet access

Two weeks ago I upgraded my adsl line with Telkom, to be told everything is done on their side a technician will come out. Then yesterday Telkom decide to cut of my internet completely....when calling their call centre numerous times (to be told they would call me back in ten minutes) the technical department blamed the orders department and the orders department blamed the technical department, I still sit without internet! <br> <br> During one of the calls the consultant said that I needed a new modem, which was still to be delivered...when asking when it would be delivered, her reply was \within 14 - 21 working days".....seriously...what am I supposed to do in the interim?<br> <br> Then I was told that the setting on the modem needed to be changed"
