Gutter Installation

I am disgusted in Emile Sieberhagen ***) from Kings Gutters. He had to install a new gutter and used incorrect gutter size and now my house roof is leaking in winter. He promises he will come by to fix it and does not pitch up. After continuous calls he does not pick up his phone. What a disgrace for gutter installers. Please don't use him, he says he will come fix his mistakes and does not pitch up, after many attempts to get him to fix my leaking gutter and messing up my ceiling in the process.
