Ultimate Contractors & Sons Ras Al Khaimah refused to address issue

I want to report a serious concern with Ultimate Contractors & Sons Ras Al Khaimah's service that I purchased on July 20, 2018 from your Schummside, 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 Lucius N., but my issue remains unresolved.
