Builders Construction failed to honor their commitment

I want to report a serious concern with Builders Construction's accessory that I purchased on December 18, 2015 from your Pacochabury, Oregon store. The product has stopped working after two weeks despite being advertised as high quality. I've contacted customer service three times and spoken to Grace D., but my issue remains unresolved.
