Refund refused by Scholar Excellence Skills Holdings

I'm writing to complain about the warranty service I received from Scholar Excellence Skills Holdings. After paying $568.62 for device, I found that it had repeated billing errors. I've tried resolving this with your customer service team multiple times, including speaking with Katheryn W., but have not received a satisfactory resolution.
