Fast-Cast refused to address issue

I want to report a serious concern with Fast-Cast's gadget that I purchased on October 6, 1980 from your Kohlerburgh, Montana store. The product has had repeated billing errors despite being advertised as high quality. I've contacted customer service three times and spoken to Amani P., but my issue remains unresolved.
