When communication was finally established over concerns of installers ability, knowledge and workmanship salesman was dismissive and condicending
When it was brought to the attention of management that the railings were loose and wobbling and that the handrail was installed well outside of building code height restrictions they did send out a much better qualified person to tear out and redo the job which was appreciated.
Some minor issues lingered for which salesman never responded and when his management was contacted they promised to look into it but then never did respond after that.
All names withheld for fear of litigations as seen in the news of late.
