We tasked them to build a small extension, shouldn't have. We had issues with them from the beginning, specifications not met, "oversights" in terms of what should been done that delayed the work, rudeness when we pointed out any issues or deviations from the specifications we supplied.
We were blamed for and insulted after every oversight that we dared to bring to the project managers attention who never ever apologized for missing or mixing up deliverables.
The initially quoted 1 month lead time was never met, due to orders messed up by the project manager (but that delay is apparently out of his hand)
Worst of that the build is still not completed, issues are not addressed, door hinges falling apart and the project manager is demanding payments that are due when the build is complete
Warranty paperwork is complete joke, details mistyped, claiming build compled in 1970...
