Today Electricien Belgium sent their new bill, and I'm in CC. I don't know what I expected, definitely i would have not expected it to be 50% of the original bill. They basically say they need a bit of hardware (I don't understand all of it, but there are some cables, wall socket boxes etc.). They also say they will need to invest again the same amount of man-hours (actually, slightly more).
Frankly, I don't know what to say about this new bill. I can't say for the hardware, but it's a gross underestimation of the work to be done. It's also sent at the end of the original work. Maybe this is normal, but I think that people with experience could flag the amount of work much earlier in the process.
I fear this will lead to frictions (again) between Electricien Belgium and the constructor.
As a bonus, in the message to the constructor, Electricien Belgium were asking for the second payment, as the hardware and the work were done.
Oh, well... I guess I need to grab some popcorn.
