Construction company halts work despite overpayment

But no: those who do not agree give the judges work and then they have to make a ruling, justify it, and also dictate it. And you never win when you give a judge work. That's what my lawyer says. What can you do about it?

No, you can't! But sorry, if someone builds a shack for 460k with an ancillary apartment that probably still needs financing, I have no sympathy! Whoever budgets tightly and cannot cover the capital service for legal disputes should please leave it! No sympathy!

but here you are partly dealing with very hardened people who immediately lose all understanding and all sympathy whenever someone does any stupidity/risk/etc.

You are absolutely right, I am a very emotional person and cannot hide it. You recognized the "shouts" well and the anger is still there today (in a milder form). Because I simply cannot understand/want to understand that it is possible to be so helpless.
But in a forum like this, isn't one looking for support and advice and possibly wanting to learn/benefit from the experiences of others? What are then, as you call them, "very hardened" people doing here who have no understanding or sympathy when others make mistakes? And then adding stupid and insulting comments, which can absolutely be spared.

That's exactly how it is: cancellation was not an option at all. Otherwise, we would have had to pay the construction company "lost profits" for the remaining work, find a new construction company to continue the existing botched job, fix the numerous defects, take over the warranty or we would have been left with no warranty for the already built parts. In addition, it would have become significantly more expensive. The overcharge would have been nicely calculated by the construction company and we would have been the fools who still would have had to pay him without any service in return. The advice given here in the forum in that direction was surely well-intentioned but not acceptable in our situation. But it was really tough. There were days when I was vomiting from morning till night, my stomach was constantly turning. I lost over 10 kg during that time. The worst time was when I found out about the second company registration and heard statements that he would rather go bankrupt than continue building for us. It was a horrible 9 months in which we did not know how things would go on.
