Warranty claim denied by Physicians Institute

I'm writing to complain about the training session I received from Physicians Institute. After paying $358.62 for application, I found that it found unauthorized charges. I've tried resolving this with your customer service team multiple times, including speaking with Douglas J., but have not received a satisfactory resolution.
