Terrible service from telkom

My dad runs a business from home, phone lines were not working from the 29.09.18. I logged the call on the 01.10.18, escalated the fault on the 03.10.18. From the 01.10.18 every day I called twice a day I got the same update stating it is with the testing centre, I even advised it was a business line it must be treated with urgency, I am still waiting for the manager to update me. Up till today the 8.10.18 I have no feedback and the problem is not solved, this is people's bread and butter, try to solve the problem instead of lying to people that you will assist with the problem. I am absolutely frustrated
