Customized products, due to their uniqueness, often involve a high degree of trust between both parties. If one party unilaterally cancels the order and does not pick up the goods, it will damage the rights and interests of the other party. Legally, it is necessary to consider the content of the order, the agreement between the two parties and relevant regulations to determine whether it constitutes a breach of contract. It is recommended that consumers actively communicate with businesses and try to resolve the issue through negotiation. If negotiation fails, they can seek legal means to protect their own rights and interests. Don't give up easily, evaluate carefully and take appropriate measures.
