Who's this mafia?
Is this the same mafia that attack and rob ambulances and burn libraries and schools?
Is it the KZN govt?
Is it the KZN people?
Seems the people in charge do not recognize the benefits of fibre.
I've seen this same thing happen with many big construction projects over the years - shopping centers are usually the most affected. It's because there's still a bunch of Zulu/whatever Chiefs here, and they demand that their people get the work. Government is too scared to do anything about it, because hundreds of thousands of votes will are being held hostage.
With big construction projects they usually just hire a bunch of locals for the grunt work, but it's not so easy with fiber, because you're in and out of the area with a smaller, tighter crew, and don't have time to develop the relationships with every stupid little induna as you work on their land for a few weeks. The new freeway between Pinetown and Durban North was held up for DECADES because of this petty tribalism.
Easier just to take your money to a province that doesn't have these problems. Whether you connect up someone in KZN or Gauteng, you're going to make the same money from the user subs, so why go to all the extra effort? Totally understandable.
