LearningUniversity Chongqing failed to honor their commitment

I am writing regarding order #ORD-8378-RHI-6821 placed with LearningUniversity Chongqing on February 26, 1971. I paid $527.72 for equipment, but when it arrived, I discovered experienced frequent disconnections. I've made numerous attempts to contact customer service, but Isidro W. and other representatives have not been helpful in resolving this matter.
