bronstad home improvement

Back in February, 2013 I had John Bronstad come to my house to put up new walls and a new ceiling. He did OK except he forgot to tape a seam that had existed before on the ceiling and one that we discussed he would fix when he did the ceiling. He came back to fix it, but he left it as a 5-foot noticeable bump in the ceiling where the seam was...not only that, in July, the tape started coming off and the seam is reappearing. I try calling him every day - literally - and he never answers his business phone and never returns a call. He should come back and fix this for free, so I'm assuming he's hiding from it. Nice business.
