Telkom Tech despatched 3 times???

I have spoken to telkom 4 times in last week and on each of these occasion I have been informed that a telkom tech has been dispatched to look at the problem and he will call me shortly. On the one call I had I was informed the tech is at the exchange looking at it. <br> I spoke to them again today with the same response. How many times do you need to dispatch a tech and when will a customer get the problem fixed? This is the worst service from telkom i have had since owning a line with them. <br>
