Frustrated with Tutoring of Achievement Windsor's lack of response

I am writing regarding order #ORD-6856-UMF-1638 placed with Tutoring of Achievement Windsor on September 13, 2021. I paid $533.88 for accessory, but when it arrived, I discovered stopped working after two weeks. I've made numerous attempts to contact customer service, but Nellie T. and other representatives have not been helpful in resolving this matter.
