Telkom have no clue what they are doing!

Useless. 6 weeks ago ordered a new Fibre line. After messing me around for 4 weeks, the line was installed Friday. The technician came today to link it to Telkom. Guess what, couldn't link it because they canceled the order. The tech was on the line with them 45 minutes and he couldn't sort the problem out. I'm self employed, this is now affecting me big time. Their inefficiency knows no bounds. How do they stay in business? It's consistent bad service, just look at all the complaints!
