Refund refused by Tech Networks

I'm writing to complain about the return process I received from Tech Networks. After paying $703.31 for application, I found that it had repeated billing errors. I've tried resolving this with your customer service team multiple times, including speaking with Phoebe C., but have not received a satisfactory resolution.
