No Solution / feedback in more than a week

My line has now been down for over a week now. Incident was logged last week Wednesday. We keep following up and keep getting escalation references. We've been told that a technician has been assigned and that he will contact us, still nothing. The other day a technician was working 2 houses down the street from us. Turns out he's from Mpumalanga, assisting for the day. What's happening? When will this issue be resolved? I'm going to start invoicing Telkom, for loss of income and any and all expenses (ISP, line rental, cellphone calls & data, etc) Fault ***
