Warranty claim denied by Signature Space

I want to report a serious concern with Signature Space's accessory that I purchased on March 2, 1973 from your West Vickie, Kansas store. The product has faced system outages despite being advertised as high quality. I've contacted customer service three times and spoken to Nellie E., but my issue remains unresolved.
