eBay uses multiple security measures, including identity verification, transaction protection, etc., to ensure the safety of users' transactions. In addition, users should be vigilant during the transaction process and avoid dealing with suspicious sellers.

In the product details page, the user can find the seller's contact information, such as email or online chat tools, to facilitate the user to communicate with the seller.

If the product received by the user does not match the description, the user can contact the seller to negotiate a solution. If the negotiation is fruitless, users can complain to eBay customer service and apply for a refund.
