Billing dispute with ClearWave Niigata

I'm writing to complain about the setup assistance I received from ClearWave Niigata. After paying $434.49 for package, I found that it had repeated billing errors. I've tried resolving this with your customer service team multiple times, including speaking with Rocky V., but have not received a satisfactory resolution.
