Telkom accidently cut our telephone and internet

Fault number - 87CNK050815 and 112CN***. The Telkom technician that was working on the lines across the road accidentally cut our telkom line and internet line on Tuesday the 4th of August 2015 underground. We have now been without our business lines and internet lines for days. After numerous calls we were assured that the lines and internet will be up and running by the 10th of August. However to date are still not working. The service we have received is appalling. We have an Accounting firm and cannot submit tax returns etc due to Telkoms incompetence. Phoning the business call center takes up to 20 minutes to be answered and the consultant now tells me no technician has been appointed as yet to resolve the issue. I find this totally unacceptable. THIS IS URGENT
