Fedup With TELKOM's SERVICE

I have logged a fault via the sms system on 21 July. We hire an adsl line from Telkom. We have internet, but no voice line, even tested the handset - no voice line. I received a fault nr. On 22 July I received an sms from Telkom informing me that the line was tested and found to be free of defects. I rep**** that it was still faulty. On Friday 24 July I dialed 10210 to find out what is going on. They told me that someone at Telkom will contact me soon. On Monday 27 July I once gain dialed and I was told that I will be contacted before 15h00. UP UNTIL NOW I AM STILL WAITING FOR TELKOM TO CONTACT ME, AND WE DO NOT HAVE A VOICE LINE. This also effect our security system as no signal can be send when the alarm go off. Are TELKOM going to cover my loss when the assurance decline any loss because of the landline not working ?? I am so frustrated with TELKOM as this is not the first time we experience problems !!
