Telkom technician closes a fault - PROBLEM REMAINS

A week ago we lodged a internet fault with Telkom and we were told it would take 24-48 business hours to fix. Now, one week later we still have no internet but apparently according to Telkom's records a technician has visited us (NOT) and the fault has been fixed and closed. IN REALITY: we had no visit from a technician and we still have no internet. They are insisting we lodge a new fault and wait. After 4 calls today we have finally been able to convince them to escalate it and again there is still no ETA on the technician. We are trying to run a business and this is unacceptable. I asked to speak with a manager numerous times and we have been given every excuse possible.
