Bad service installing ADSL

I have had a router installed last week Friday. I have been struggling to get it activated. In essence I am paying for a service that I cant use. When I called the technician yesterday, he advised that the router cannot be activated until the ticket is closed. I then got a call from a consultant attempting to sort out my issue. I advised her that she should get in contact with my sister that would be home to give all the info. I explained that due to them working office hours I wont be able to set it up because I will not be home before 5pm. They assured me that they would call my sister at 2pm yesterday and again no call. Telkom service is pathetic and I have been struggling with this since May 27th. If this is not sorted by Friday I will be cancelling the service.
