Telkom damaging my takeaway business! PLEASE HELP!

I own a Col 'Cacchio Pizza takeaway restaurant. Phone orders make up 85% of my business. My telephone line went down on Friday, 6th March. I reported it immediately. Since then - I have followed up with the Telkom call centre daily as my business is suffering. Call centre agents kept telling me how busy they are. It took until 18 March to have the fault assigned to a technician and when someone came out today - they told me its a problem with the underground cable and they cannot fix it. They now apparently have to speak to people in the cabling division to see if they know how to solve the issue. I have no contact number for the cabling division and no way of knowing if, or when anyone will actually attend to the problem. <br> <br> I have investigated every conceivable angle to get my business back on track including requesting another Telkom line which - interestingly enough - they were not too busy to sort out (since it was new business). That line does not work either due to the same cabling fault. <br> <br> Telkom I'm desperate. What do I need to do to get my issue sorted out? My ref number is 504CWZ090315. My escalation number is 678573. Perhaps this public naming and shaming will help?
