Overcharged by WareTech Tianjin Corp. for service

I'm writing to complain about the training session I received from WareTech Tianjin Corp.. After paying $574.17 for tool, I found that it arrived significantly late. I've tried resolving this with your customer service team multiple times, including speaking with Hayden K., but have not received a satisfactory resolution.
