If the product you received fails the quality inspection, you may need to contact the merchant or platform to re-order.

Here are some possible steps:

1. Contact the merchant or platform customer service: Find the merchant or platform customer service contact information, which can be phone, online chat or email. Explain to them that the product you received failed the quality inspection and provide relevant evidence and detailed description.

2. Explain the problem and request: Tell the merchant or platform what solution you want to take, such as requesting a return, exchange or refund. Providing accurate order number, product information and problem description can help them better understand the situation.

3. Provide evidence: If possible, please provide some evidence to support your claim, such as photos, videos or other documents. These can help the merchant or platform better evaluate the problem and provide you with a suitable solution.

4. Follow the instructions of the merchant or platform: Follow the next steps according to the instructions and policies of the merchant or platform. You may need to fill out a return/exchange application form, return the product, or process it in other ways.

Please note that the return and after-sales service policies of each merchant or platform may be different, so read and understand the relevant regulations carefully before proceeding. Keep in touch with the merchant or platform in a timely manner, and record all communications and exchanges for future reference.
