1. Confirm the contract and agreement: carefully check the contract and agreement signed with the paper company. Check whether the amount, payment method and time of the final payment of the paper are clear. Make sure you know your rights and responsibilities.

2. Communication and consultation: communicate with the paper agency to clearly express their dissatisfaction and doubts. Explain why you are dissatisfied with their service, and put forward your requirements and expectations. Try to find a solution in a friendly and rational way.

3. Seek legal help: If communication and consultation cannot solve the problem, you can seek legal help. Consult a lawyer or relevant legal institutions to understand their rights and interests and legal channels. They can give you professional advice and help according to your specific situation.

4. Alarm and complaint: If you think that the behavior of the paper agency involves fraud, fraud or other illegal acts, you can report the case to the local police and complain to the relevant regulatory agencies or consumer protection organizations. Provide relevant evidence and contract documents to support your complaint.
