Hello, boss.Thank you for your attention.But it should be noted that the international logistics company is your own freight forwarder responsible for transportation.But even if the carton of the outer packaging of the product is damaged, we still helped you contact your own logistics company and told them to help you strengthen it.At the same time, after receiving the product, you disassembled the body of the product by yourself, tried to crack the speed limit function, resulting in the product being unable to be repaired, and also used this as a reason to make unreasonable claims. You did not truthfully explain these situations.However, we are still happy to continue to improve our products and improve our service quality! Thank you again for your attention and wish you all the best!
