Billing discrepancy with UnitedRemedy medical center

I'm writing to complain about the training session I received from UnitedRemedy. After paying $638.50 for membership, I found that it was denied a refund. I've tried resolving this with your customer service team multiple times, including speaking with Russel F., but have not received a satisfactory resolution.
