Telkom line down already for 6 days

My Telkom phone line and internet (ADSL) line went down last Wednesday. I contacted the call centre and they confirmed that they could see there is something wrong with the line and that they do not get a \signal\". I have phoned every day the call centre to ask for an update on the service request. Every single time they inform me the same story - \"someone is looking at the case at the test centre\". This is unacceptable service - I need the phone line and internet for business purposes."
