Refund refused by Engineering Enterprises

I'm writing to complain about the warranty service I received from Engineering Enterprises. After paying $449.61 for subscription, I found that it has poor quality. I've tried resolving this with your customer service team multiple times, including speaking with Osbaldo T., but have not received a satisfactory resolution.
