why are you posting here instead of getting an attorney and getting this resolved, getting the build you were supposed to get to begin with? I mean, that's why these companies have insurance.
it sounds like you got screwed and your simply accepting it and now trying to make due. I don't think you should. unless you paid them to do a ***** job like they did, you should sue and get it redone properly.
don't get me wrong, if you want to leave what was done to you as is, that's fine and i'll respect that as it's your choice to do so. I wouldn't touch it until it's legally resolved. the nature of my post is because you didn't say what you were doing about the wrong doings to you, your project and your home. you only appear to be asking for workarounds to what was done as if you have simply accepted it.
best of luck to you.
