1, Stay calm and polite: No matter how unreasonable the customer's request is, you should stay calm and polite. Don't argue or get emotional with customers, which may make customers insist on their own requirements more.
2. Listen to the customer's requirements: Listen carefully to the customer's requirements before rejecting the customer. This can show respect for customers and better understand their needs and expectations.
3. Clear rejection: Once it is determined that the customer's requirements are unreasonable, it is necessary to explicitly and directly reject the customer. Don't use vague language, which may make customers misunderstand themselves.
