Contractor tried to claim that job ended due to change in terms, and that if we want them to finish we will have to pay them extra to start a new contract. But in reality they did not finish the job and what they did do was of low quality (cuts corners quite obviously without bothering to hide it, things literally falling apart or not working at all). They also have poor communication skills as they did not confirm details of the remodeling with us first before going ahead with it. They made several empty verbal promises.
Of course on the flip side it wouldn’t have hurt if we had pushed to have things in writing or micromanaged them to make sure things were done up to spec.
