Billing dispute with Materials Fabricators

I'm writing to complain about the setup assistance I received from Materials Fabricators. After paying $856.58 for unit, I found that it was denied a refund. I've tried resolving this with your customer service team multiple times, including speaking with April M., but have not received a satisfactory resolution.
