This evidence may play a key role in the subsequent rights defense process.
2. Contact the seller: You can contact the seller of Yangzi Beer directly, explain to them the situation that you have been cheated, and ask them what solution they have. If they can offer a reasonable solution such as a refund or an exchange, then you can consider accepting their solution.
3. Complaints and reports: If the seller of Yankee Beer does not provide a reasonable solution, you can file a complaint or report it to the relevant authorities, such as to the market regulator, the Consumer Association, or to the relevant government departments. These organizations can help you further understand your rights and feasible solutions.
4. Legal: If none of the above methods can solve the problem, you can consider legal ways to protect your rights. You can go to the local court to file a lawsuit and ask Yangzi Beer to compensate for the loss. In this process, you need to find a lawyer to help you deal with legal matters.
