He told me that this review had to be removed for me to receive a partial refund. Which I did. To finish the extension, I have retained the sub contractors that he originally employed as their work has been exemplary. I have spent the past month repeating work that he undertook personally (roofing/plumbing) and am massively out of pocket even with a refund. HENCE THE ONE STAR
