Step-by-step explanation:
The first and most important thing to remember when dealing with a difficult client is to control your temper. Choose your words carefully so as not to inflame the situation, stay as calm as possible, and listen to the other side of the story. Avoid suggesting that you're right and the other person is wrong; remain open and respectful. Try asking open-ended questions to learn more about the other person's position, rather than stating your case. Restate what you heard the person say to let them know you were listening and to avoid misunderstandings. Focus on solving the problem, not blaming the other person. If you're not able to resolve the conflict, you may choose to speak with your supervisor or HR department.
