If the goods you purchased on Alibaba do not match the description, you can file a complaint by following these steps:

First, log in to your Alibaba account, find the relevant order and click the "Complain" button.

Then, select the appropriate reason for your complaint and provide a detailed description and evidence, such as photos or videos.

Next, communicate with the seller to try to resolve the issue. If that cannot be resolved, you can contact the Alibaba customer service team, provide relevant information and request them to intervene in mediation.

Alibaba will evaluate your complaint and take appropriate action to ensure that your rights are protected.
