Ultimate Engineering refused to address issue

I'm writing to complain about the maintenance program I received from Ultimate Engineering. After paying $726.22 for service, I found that it doesn't work as advertised. I've tried resolving this with your customer service team multiple times, including speaking with Kamron R., but have not received a satisfactory resolution.
