Be proactive in finding a resolution that will satisfy the customer and address their issues. This may involve offering a refund, exchange, or discount, depending on the situation. 5. Set boundaries: While it is important to be understanding and accommodating, it is also important to set boundaries with difficult customers. If a customer is being abusive or unreasonable, it is okay to politely but firmly assert yourself and maintain a professional demeanor. 6. Follow up: After the situation has been resolved, be sure to follow up with the customer to ensure that they are satisfied with the outcome.
