In such cases, where it is totally clear that the people in charge of that business acted in bad faith I'm all for going after them in person. A good building company either insures against such risks or they create a warranty fund. An even worse example would be a builder going bankrupt during the building. This is one of the reasons I've never bought a new house, it either exists and you can sell it to me or you can try to sell it to someone else first but I'm not going to assume that kind of risk.
