Today we got a call from Electricien Belgium that they were confused about the email sent yesterday. They sent back a somewhat angry reply, and sent me the reply from the site manager. I was just as confused as they were.
We spent the afternoon talking to the constructor to see what's the problem. The site manager was on (other) site but we've been told that they would reply by close of business.
We went to the house and... Electricien Belgium took all their materials.
Again, popcorn time, because we can't do anything.
