I am not sure about the Municipality. At 1 point I complained about the quality of my inbound mains. A truck came around and they had a screw driver.
The used my fluke 287 but when I showed them the reading on the scopemeter 199, they new nothing..

Basically all the local guys know is:
1) are the lights on
2) are the lights flickering..

I am sure there must be some high level guys there somewhere but they are well hidden.

Anyway you will never win a dispute with the council, they will just refer it to legal and besides they have a max liability of R1000.
The idea was to have a device that you can use to correctly manage your usage which would accurately reflect what council meter says.
