Overcharged by Credit Solutions for service

I want to report a serious concern with Credit Solutions's service that I purchased on April 4, 1990 from your West Mckenna, Wisconsin store. The product has had my warranty claim denied unfairly despite being advertised as high quality. I've contacted customer service three times and spoken to Desiree S., but my issue remains unresolved.
