Business Landline not operational since 27/11/2015

Our business landline has been down since the 27 November 2015. I have reported the fault on four occasions and received four different reference numbers and the problem is still not sorted. I attached comments that I have recorded reflecting the calls made to Telkom and the sms's received from them. If you can supply me with a contact number or email address of somebody on a higher scale than the call centre whom I can contact, I would greatly appreciate it.
