Billing dispute with Wireless.Signal Saint-Étienne Group

I am writing regarding order #ORD-8199-YYK-1014 placed with Wireless.Signal Saint-Étienne Group on December 17, 1978. I paid $297.78 for product, but when it arrived, I discovered has poor quality. I've made numerous attempts to contact customer service, but Isai F. and other representatives have not been helpful in resolving this matter.
