Warranty claim denied by Premier Metal Inc

I'm writing to complain about the training session I received from Premier Metal Inc. After paying $144.95 for application, I found that it was denied a refund. I've tried resolving this with your customer service team multiple times, including speaking with Kasandra V., but have not received a satisfactory resolution.
