Adsl setup disaster

Telkom moved my adsl and gabe me a new number, this worked and was done in 1 weeks time. The line only worked for 2 hours then it stopped. Since them been on the phone for more than 10 hours calling everyday to find out what the problem is. They've told me that the line is somebody elses, the line has problems and that the line has not been activated yet. Technicians was dispatched 4 times already but never showed up. Sick of their **** service and then have the whits to charge me for it!!! Till date no resolution and nobody can tell me what to do or who to call.
