If the product has abnormal faults during the warranty period, don't go to the repairer directly, you should go to the manufacturer's headquarters for after-sales maintenance.

If you go directly to the local repairer, it is easy to be deceived and the maintenance is not guaranteed.

Report to the manufacturer's headquarters for after-sales maintenance, and the after-sales maintenance will assign a local contracted repairer to conduct on-site inspection and maintenance. In this way, the behavior of the maintainer is under the supervision of the manufacturer, and it is unlikely to be chaotic.
