Waiting for repairs

I reported our faulty business line 3 weeks ago and to date have escalated the fault 3 times and still i have not heard a word from Telkom about when they will be fixing our line. I called Telkom everyday this week and every day the promised someone would call me back to arrange and still nothing. We are desperate now as this is a work line. I cant believe how useless Telkom has been and how difficult it is to reach an agent. So unhappy with this lack of service.
