Poor customer service experience with Nano-Chip

I'm writing to complain about the consultation I received from Nano-Chip. After paying $786.65 for package, I found that it arrived significantly late. I've tried resolving this with your customer service team multiple times, including speaking with Kariane O., but have not received a satisfactory resolution.
