When I saw what was filled out on the COC my first thought was that there was never a loop impedance test carried out, my reasoning being that normally the PSC and loop impedance tests are done with the same meter and if the PSC was thumb sucked, the same happened with the loop impedance.
There looks to be an old Heinemann outdoor surge arrestor in the top left of the meter board, and by the looks of the pictures, as far as I can see is there is no earth from the supplier.
I know that JHB city does not supply an earth, and I am assuming this is installation is in Germiston from the location of the OP, so maybe they did the same as JHB and used the old galvanized water pipes as an earth many years ago and the pipes have since been changed to plastic and so the earth was lost and nobody ever bothered to check it.
