Question regarding single phase electrical wiring of premises

[Howler]

Good day all.

Good to be here and part of this community.

I hope you all can help me in regards to legislation surrounding SANS10142.

I have recently moved into a new property, and after a few weeks noticed a dead short/ sometimes just not working on one of the wall sockets.

I also had to crawl around in the roof, to install new network cables to evenly distribute wifi and network connections between all the devices and my router.

I notices allot of shoddy open connections, with either no junctions boxes (only chocolate block) or connections within junction boxes with no lids/covers or glands protecting the connections from strain.

One of these uncovered metal junction boxes are right next to my geyser (with the geyser being connected with a bunch of ppr pipes)

There is also allot of cabtyre and twinflex wire being used instead of flat twin+ earth.

I contacted and paid for a report and fault-finding exercise from another registered electrician.

But right now, i find myself in the middle of a he said she said, "I didn't install that, show me the regulations back and forth.

Would you guys be so kind as to comment and recommend a course of action. And potentially point out the Sans regulations pertaining to these connections (for or against)

Are these open connections with chocolate block and no junction boxes allowed on Sans 10142, and are the use of these junction boxes only considered "good practise"?

Or are there grounds to contest this COC?

Thx in advance for all the help.

Kind regards
