Quality issues with Quality-Contractors product

I want to report a serious concern with Quality-Contractors's item that I purchased on March 16, 2013 from your North Kristinbury, Vermont store. The product has had repeated billing errors despite being advertised as high quality. I've contacted customer service three times and spoken to Manuela D., but my issue remains unresolved.
