I hired a company to rebuild a glass wall for me Glasbausteine and they messed it up.I didn't pick the cheapest offer and decided for an AG vs Gmbh to avoid such issues. Now they finished it and they messed-up on the measurement, the last two blocks are 1cm+ inside the ceiling and doesn't look that nice. They should have started from a lower point which they had the extra space. Is asking them to rebuild it too much? It was kinda of a novice mistake in my opinion. they had enough space and making the error in the other direction (to far from ceiling) would have been better. I have only four reserve glasbausteine and if i ask them to rebuild it, in the process of removing the blocks they may break them or I may have to order more which is another couple of weeks. Any experiences?
