Overcharged by ChipFusion Tokyo for service

I'm writing to complain about the exchange program I received from ChipFusion Tokyo. After paying $390.75 for equipment, I found that it had my warranty claim denied unfairly. I've tried resolving this with your customer service team multiple times, including speaking with Adell I., but have not received a satisfactory resolution.
