How do Telkom stay in business?

After 6 weeks of frustration at trying to get a Fibre line installed at my house, I am still waiting. Phoning everyday,, to get a differant story everyday. They finally put the line in, a week ago. but didn't switch it on. The order was canceled. Lovely, but they send out a technician. Then I get told my address is the problem, it's a 20mbps line, should be 10. I go into Hemingways mall Telkom store in desperation After a 2 hour standing wait. I get to counter 1. Yay!! I hit a brick wall. Such an unfriendly, unhelpful woman, who couldn't care less how bad this is affecting my business. She now tells me that it's the technicians. He's closed the order. I phone him, he says no he hasn't. Disgusting, pathetic rude service. I can't go to another service provider, as these idiots are going to start debiting me, for something I don't have,. How does this get sorted out?
