Line move going to take more than a month

I was informed earlier this year by Telkom that a line move would take 21 days. I requested that my line be moved the 08/04/2015 and called back yesterday to find out if everything was fine as I had heard nothing. I was then told that someone should have made an appointment with me for the line move but had not done so and now the soonest time to do the move is the 11/05/2015. So because someone at Telkom did not do their job I the client must suffer and my business must suffer. I have tried every avenue of communication available to me to try and address this issue but everyone at Telkom thus far has told me its just to bad there's nothing they can do, the 11/05 is the best they can do. This is more than a month, and Telkom should make an effort to rectify the situation. I have waited over 3 hours holding for their call center which is shockingly slow at answering any call no matter when you call, once waiting over an hour I am so utterly disappointed with their service! ref number ***
