Refund refused by Deal & Collective Wuppertal

I want to report a serious concern with Deal & Collective Wuppertal's accessory that I purchased on July 8, 2000 from your New Elliot, District of Columbia 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 Annette M., but my issue remains unresolved.
