The most effective way for BYD to complain.

BYD officials communicate directly, complain to relevant institutions or platforms, and take legal measures.

1, BYD official direct communication: First of all, you can directly contact BYD customer service department, state the problem in detail by calling the official customer service phone or sending an email and express your dissatisfaction. In the process of communication, it is necessary to provide relevant evidence such as car purchase contracts, invoices and maintenance records, so that officials can better understand the problems and give reasonable solutions.

2. Complain to relevant institutions or platforms: If communication with BYD officials is fruitless, you can complain to consumer associations, industrial and commercial bureaus and other relevant institutions. These institutions will investigate according to relevant laws and regulations and give corresponding treatment results. In addition, you can also choose to publish complaint information on a third-party complaint platform, such as the automobile complaint network. These platforms usually have a dedicated person to handle complaints and give feedback as soon as possible.

3. Legal channels: If the problem is serious and cannot be solved by the above methods, you can choose to take legal channels. You can bring a lawsuit to the court and ask BYD to bear the corresponding legal responsibility. In this process, it is necessary to prepare relevant evidence and seek the help of professional lawyers.
