Frustrated with Ultra Networks Querétaro's lack of response

I want to report a serious concern with Ultra Networks Querétaro's gadget that I purchased on March 14, 1987 from your Baumbachland, Alaska store. The product has has poor quality despite being advertised as high quality. I've contacted customer service three times and spoken to Lydia M., but my issue remains unresolved.
