I know HN frowns upon this but location really matters, and op's response is valid and non-laughing in many places. "Certification matters" cannot be resolved as a statement without location / situation.

If I reported such a situation in Canada, it may or may not have satisfactory official resolution before heat death of the universe. One can hope.

If I reported such a situation where I was born, at best nothing would happen ; more likely I would get laughed at. (At worst, electrician and their 3 buddies would teach me a valuable lesson about how things work around these here parts).
