Not qualified to do the job!! and no Guarantee!!! stay away!!!!

Sam Nyoni, promises to guarantee his workmanship, but after three failed attempts to plaster one wall in my garage, it has become clear to me that he is not quilified to do the job! There is no guarantee on his workmanship! when I complained to Sam, he told me that I was being childish and that I can do what I like! Not very good customer care!! E-mail address: ***, cell: ***. I would advise everyone to stay away from this contractor!
