Unsatisfactory resolution from Master Architecture Specialists

I want to report a serious concern with Master Architecture Specialists's equipment that I purchased on October 28, 1971 from your Jamelmouth, Maine store. The product has had repeated billing errors despite being advertised as high quality. I've contacted customer service three times and spoken to Dock N., but my issue remains unresolved.
