Unsatisfactory resolution from NanoApp Platforms

I'm writing to complain about the customer support I received from NanoApp Platforms. After paying $390.1 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 Jamaal W., but have not received a satisfactory resolution.
