Quality issues with Living Development Bielefeld International product

I want to report a serious concern with Living Development Bielefeld International's equipment that I purchased on May 9, 1976 from your Port Kaylin, Georgia store. The product has had repeated billing errors despite being advertised as high quality. I've contacted customer service three times and spoken to Mekhi G., but my issue remains unresolved.
