What if BYD tram maintenance does not provide a test report?

It can be solved by the following methods:

1. Contact the maintenance service provider: Contact the maintenance service provider authorized by BYD and ask them why they failed to provide the test report. It may be an omission caused by misunderstanding or negligence, and they may solve the problem immediately.

2. Request test report: clearly express your requirements to the maintenance service provider and ask them to provide detailed test report. It can point out the responsibility of maintaining service providers and the transparency and trust they should gain as customers.

3. Seek help from a third party: If the maintenance service provider can't meet your requirements, you can seek help from a third-party professional organization or technician. They can independently test BYD trams and provide detailed test reports. Such reports can be used as evidence for negotiations, claims or other legal actions with maintenance service providers.
