ADSL line down for more than 10 days

My ADSL line and Data goes through Cybersmart after reporting the problem on the 18th of November. Cybersmart keeps closing the call so they don't go over the SLA violation. Keeps opening a new call every time I phone to check up. When I phoned Telkom my line was never reported by Cybersmart. I'm on the 10mbps package and been down for more than half the month but still get my invoice for full month usage and full line rental. They don't attend to any problems and has NO SERVICE to get me back up. Phoned them again today and all they can do is blame Telkom and they can escalate but doesn't happen.
